Version 1.33.0 (2019-02-28)
|
|
|
|
|
==========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
- [You can now use the `cfg(target_vendor)` attribute.][57465] E.g.
|
2019-02-28 01:09:32 +01:00
|
|
|
`#[cfg(target_vendor="apple")] fn main() { println!("Hello Apple!"); }`
|
2019-02-20 15:51:22 +01:00
|
|
|
- [Integer patterns such as in a match expression can now be exhaustive.][56362]
|
|
|
|
|
E.g. You can have match statement on a `u8` that covers `0..=255` and
|
2019-02-28 01:09:32 +01:00
|
|
|
you would no longer be required to have a `_ => unreachable!()` case.
|
2019-02-06 15:42:21 +01:00
|
|
|
- [You can now have multiple patterns in `if let` and `while let`
|
|
|
|
|
expressions.][57532] You can do this with the same syntax as a `match`
|
|
|
|
|
expression. E.g.
|
|
|
|
|
```rust
|
|
|
|
|
enum Creature {
|
2019-02-20 15:51:22 +01:00
|
|
|
Crab(String),
|
|
|
|
|
Lobster(String),
|
|
|
|
|
Person(String),
|
2019-02-06 15:42:21 +01:00
|
|
|
}
|
|
|
|
|
|
|
|
|
|
fn main() {
|
2019-02-20 15:51:22 +01:00
|
|
|
let state = Creature::Crab("Ferris");
|
2019-02-06 15:42:21 +01:00
|
|
|
|
2019-02-20 15:51:22 +01:00
|
|
|
if let Creature::Crab(name) | Creature::Person(name) = state {
|
2019-02-22 17:50:18 +01:00
|
|
|
println!("This creature's name is: {}", name);
|
2019-02-20 15:51:22 +01:00
|
|
|
}
|
2019-02-06 15:42:21 +01:00
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
- [You can now have irrefutable `if let` and `while let` patterns.][57535] Using
|
|
|
|
|
this feature will by default produce a warning as this behaviour can be
|
|
|
|
|
unintuitive. E.g. `if let _ = 5 {}`
|
2019-02-22 17:50:18 +01:00
|
|
|
- [You can now use `let` bindings, assignments, expression statements,
|
|
|
|
|
and irrefutable pattern destructuring in const functions.][57175]
|
2019-02-20 15:51:22 +01:00
|
|
|
- [You can now call unsafe const functions.][57067] E.g.
|
2019-02-06 15:42:21 +01:00
|
|
|
```rust
|
2019-02-07 10:05:15 +01:00
|
|
|
const unsafe fn foo() -> i32 { 5 }
|
2019-02-06 15:42:21 +01:00
|
|
|
const fn bar() -> i32 {
|
2019-02-22 17:50:18 +01:00
|
|
|
unsafe { foo() }
|
2019-02-06 15:42:21 +01:00
|
|
|
}
|
|
|
|
|
```
|
2019-02-20 15:51:22 +01:00
|
|
|
- [You can now specify multiple attributes in a `cfg_attr` attribute.][57332]
|
|
|
|
|
E.g. `#[cfg_attr(all(), must_use, optimize)]`
|
|
|
|
|
- [You can now specify a specific alignment with the `#[repr(packed)]`
|
|
|
|
|
attribute.][57049] E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a struct
|
|
|
|
|
with an alignment of 2 bytes and a size of 6 bytes.
|
2019-02-13 10:54:13 +01:00
|
|
|
- [You can now import an item from a module as an `_`.][56303] This allows you to
|
2019-02-06 15:42:21 +01:00
|
|
|
import a trait's impls, and not have the name in the namespace. E.g.
|
|
|
|
|
```rust
|
|
|
|
|
use std::io::Read as _;
|
|
|
|
|
|
|
|
|
|
// Allowed as there is only one `Read` in the module.
|
|
|
|
|
pub trait Read {}
|
|
|
|
|
```
|
2019-02-28 01:09:32 +01:00
|
|
|
- [You may now use `Rc`, `Arc`, and `Pin` as method receivers][56805].

|
|
|
|
|
command line argument.][56351]
|
|
|
|
|
- [The mininum required LLVM version has been bumped to 6.0.][56642]
|
|
|
|
|
- [Added support for the PowerPC64 architecture on FreeBSD.][57615]
|
|

Compatibility Notes
|
|
|
|
|
-------------------
|
2019-02-21 14:10:24 +01:00
|
|
|
- The methods `str::{trim_left, trim_right, trim_left_matches, trim_right_matches}`
|
|
|
|
|
are now deprecated in the standard library, and their usage will now produce a warning.
|
|
|
|
|
Please use the `str::{trim_start, trim_end, trim_start_matches, trim_end_matches}`
|
|
|
|
|
methods instead.
|
2019-02-28 01:09:32 +01:00
|
|
|
- The `Error::cause` method has been deprecated in favor of `Error::source` which supports
|
|
|
|
|
downcasting.
|
2019-03-06 01:43:30 +01:00
|
|
|
- [Libtest no longer creates a new thread for each test when
|
|
|
|
|
`--test-threads=1`. It also runs the tests in deterministic order][56243]

|
#### 2018 edition
|
|
|
|
|
- [You can now use the `?` operator in macro definitions.][56245] The `?`
|
|
|
|
|
operator allows you to specify zero or one repetitions similar to the `*` and
|
|
|
|
|
`+` operators.
|
2019-01-10 23:07:38 +01:00
|
|
|
- [Module paths with no leading keyword like `super`, `self`, or `crate`, will
|
|
|
|
|
now always resolve to the item (`enum`, `struct`, etc.) available in the
|
|
|
|
|
module if present, before resolving to a external crate or an item the prelude.][56759]
|
|
|
|
|
E.g.
|
|
|
|
|
```rust
|
|
|
|
|
enum Color { Red, Green, Blue }
|
|
|
|
|
|
|
|
|
|
use Color::*;
|
|
|
|
|
```

|
|
|
|
|
|
|
|
#### All editions
|
|
|
|
|
- [You can now match against `PhantomData<T>` types.][55837]
|
|
|
|
|
- [You can now match against literals in macros with the `literal`
|
|
|
|
|
specifier.][56072] This will match against a literal of any type.
|
|
|
|
|
E.g. `1`, `'A'`, `"Hello World"`
|
2019-02-28 01:09:32 +01:00
|
|
|
- [Self can now be used as a constructor and pattern for unit and tuple structs.][56365] E.g.
|
2019-01-09 16:12:12 +01:00
|
|
|
```rust
|
|
|
|
|
struct Point(i32, i32);
|
|
|
|
|
|
|
|
|
|
impl Point {
|
|
|
|
|
pub fn new(x: i32, y: i32) -> Self {
|
|
|
|
|
Self(x, y)
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
pub fn is_origin(&self) -> bool {
|
|
|
|
|
match self {
|
|
|
|
|
Self(0, 0) => true,
|
|
|
|
|
_ => false,
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
- [Self can also now be used in type definitions.][56366] E.g.
|
|
|
|
|
```rust
|
|
|
|
|
enum List<T>
|
|
|
|
|
where
|
2019-01-10 10:08:32 +01:00
|
|
|
Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
|
2019-01-09 16:12:12 +01:00
|
|
|
{
|
2019-01-10 23:28:18 +01:00
|
|
|
Nil,
|
|
|
|
|
Cons(T, Box<Self>) // likewise here
|
2019-01-09 16:12:12 +01:00
|
|
|
}
|
|
|
|
|
```
|
2019-01-10 10:08:07 +01:00
|
|
|
- [You can now mark traits with `#[must_use]`.][55663] This provides a warning if
|
|
|
|
|
a `impl Trait` or `dyn Trait` is returned and unused in the program.

|
|
|
|
- [`PathBuf` now implements `FromStr`.][55148]
|
|
|
|
|
- [`Box<[T]>` now implements `FromIterator<T>`.][55843]
|
|
|
|
|
- [The `dbg!` macro has been stabilized.][56395] This macro enables you to
|
|
|
|
|
easily debug expressions in your rust program. E.g.
|
|
|
|
|
```rust
|
|
|
|
|
let a = 2;
|
|
|
|
|
let b = dbg!(a * 2) + 1;
|
|
|
|
|
// ^-- prints: [src/main.rs:4] a * 2 = 4
|
|
|
|
|
assert_eq!(b, 5);
|
|
|
|
|
```
|
|
|

2018-11-04 18:48:30 +01:00
|
|
|
- [New lifetime elision rules now allow for eliding lifetimes in functions and
|
|
|
|
|
impl headers.][54778] E.g. `impl<'a> Reader for BufReader<'a> {}` can now be
|
|
|
|
|
`impl Reader for BufReader<'_> {}`. Lifetimes are still required to be defined
|
|
|
|
|
in structs.
|
|
|
|
|
- [You can now define and use `const` functions.][54835] These are currently
|
|
|
|
|
a strict minimal subset of the [const fn RFC][RFC-911]. Refer to the
|
|
|
|
|
[language reference][const-reference] for what exactly is available.
|
|
|
|
|
- [You can now use tool lints, which allow you to scope lints from external
|
|
|
|
|
tools using attributes.][54870] E.g. `#[allow(clippy::filter_map)]`.
|
|
|
|
|
- [`#[no_mangle]` and `#[export_name]` attributes can now be located anywhere in
|
|
|
|
|
a crate, not just in exported functions.][54451]
|

`From` trait.][54240] E.g. `u8` now implements `From<NonZeroU8>`.
|
|
|
|

|
Language
|
|
|
|
|
--------
|
|
|
|
|
- [Procedural macros are now available.][52081] These kinds of macros allow for
|
2018-10-23 13:53:48 +02:00
|
|
|
more powerful code generation. There is a [new chapter available][proc-macros]
|
|
|
|
|
in the Rust Programming Language book that goes further in depth.
|
2018-09-17 18:44:04 +02:00
|
|
|
- [You can now use keywords as identifiers using the raw identifiers
|
2018-10-23 13:53:48 +02:00
|
|
|
syntax (`r#`),][53236] e.g. `let r#for = true;`
|
2018-09-17 18:44:04 +02:00
|
|
|
- [Using anonymous parameters in traits is now deprecated with a warning and
|
|
|
|
|
will be a hard error in the 2018 edition.][53272]
|
|
|
|
|
- [You can now use `crate` in paths.][54404] This allows you to refer to the
|
2018-10-23 13:53:48 +02:00
|
|
|
crate root in the path, e.g. `use crate::foo;` refers to `foo` in `src/lib.rs`.
|
|
|
|
|
- [Using a external crate no longer requires being prefixed with `::`.][54404]
|
|
|
|
|
Previously, using a external crate in a module without a use statement
|
|
|
|
|
required `let json = ::serde_json::from_str(foo);` but can now be written
|
2018-09-17 18:44:04 +02:00
|
|
|
as `let json = serde_json::from_str(foo);`.
|
|
|
|
|
- [You can now apply the `#[used]` attribute to static items to prevent the
|
2018-10-23 13:53:48 +02:00
|
|
|
compiler from optimising them away, even if they appear to be unused,][51363]
|
2018-09-17 18:44:04 +02:00
|
|
|
e.g. `#[used] static FOO: u32 = 1;`
|
|
|
|
|
- [You can now import and reexport macros from other crates with the `use`
|
|
|
|
|
syntax.][50911] Macros exported with `#[macro_export]` are now placed into
|
|
|
|
|
the root module of the crate. If your macro relies on calling other local
|
2018-10-23 13:53:48 +02:00
|
|
|
macros, it is recommended to export with the
|
|
|
|
|
`#[macro_export(local_inner_macros)]` attribute so users won't have to import
|
|
|
|
|
those macros.
|
2018-09-17 18:44:04 +02:00
|
|
|
- [You can now catch visibility keywords (e.g. `pub`, `pub(crate)`) in macros
|
|
|
|
|
using the `vis` specifier.][53370]
|
2018-10-23 13:53:48 +02:00
|
|
|
- [Non-macro attributes now allow all forms of literals, not just
|
|
|
|
|
strings.][53044] Previously, you would write `#[attr("true")]`, and you can now
|
2018-09-17 18:44:04 +02:00
|
|
|
write `#[attr(true)]`.
|
|
|
|
|
- [You can now specify a function to handle a panic in the Rust runtime with the
|
|
|
|
|
`#[panic_handler]` attribute.][51366]

Security Notes
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
- The standard library's `str::repeat` function contained an out of bounds write
|
|
|
|
|
caused by an integer overflow. This has been fixed by deterministically
|
|
|
|
|
panicking when an overflow happens.
|
|
|
|
|
|
|
|
|
|
Thank you to Scott McMurray for responsibily disclosing this vulnerability to
|
|
|
|

us.

===========================

|
|
|
|
Language
|
|
|
|
|
--------
|
2018-06-26 14:41:32 +02:00
|
|
|
- [The `#[repr(transparent)]` attribute is now stable.][51562] This attribute
|
2018-06-22 22:23:17 +02:00
|
|
|
allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as
|
|
|
|
|
the inner type across Foreign Function Interface (FFI) boundaries.
|
|
|
|
|
- [The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved
|
|
|
|
|
and can now be used as identifiers.][51196]
|
2018-06-26 14:41:32 +02:00
|
|
|
- [The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
|
|
|
|
|
stable.][51241] This will allow users to specify a global allocator for
|
2018-06-22 22:23:17 +02:00
|
|
|
their program.
|
|
|
|
|
- [Unit test functions marked with the `#[test]` attribute can now return
|
|
|
|
|
`Result<(), E: Debug>` in addition to `()`.][51298]
|
2018-06-26 14:41:32 +02:00
|
|
|
- [The `lifetime` specifier for `macro_rules!` is now stable.][50385] This
|
|
|
|
|
allows macros to easily target lifetimes.

Compiler
|
|
|
|
|
--------
|
2018-06-26 14:41:32 +02:00
|
|
|
- [The `s` and `z` optimisation levels are now stable.][50265] These optimisations
|
2018-06-22 22:23:17 +02:00
|
|
|
prioritise making smaller binary sizes. `z` is the same as `s` with the
|
|
|
|
|
exception that it does not vectorise loops, which typically results in an even
|
|
|
|
|
smaller binary.
|
2018-06-26 14:41:32 +02:00
|
|
|
- [The short error format is now stable.][49546] Specified with
|
2018-06-22 22:23:17 +02:00
|
|
|
`--error-format=short` this option will provide a more compressed output of
|
|
|
|
|
rust error messages.
|
|
|
|
|
- [Added a lint warning when you have duplicated `macro_export`s.][50143]
|
|
|
|
|
- [Reduced the number of allocations in the macro parser.][50855] This can
|
|
|
|
|
improve compile times of macro heavy crates on average by 5%.

Libraries
|
|
|
|
|
---------
|
|
|
|
|
- [Implemented `Default` for `&mut str`.][51306]
|
|
|
|
|
- [Implemented `From<bool>` for all integer and unsigned number types.][50554]
|
|
|
|
|
- [Implemented `Extend` for `()`.][50234]
|
|
|
|
|
- [The `Debug` implementation of `time::Duration` should now be more easily
|
|
|
|
|
human readable.][50364] Previously a `Duration` of one second would printed as
|
2018-06-22 23:36:01 +02:00
|
|
|
`Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`.
|
2018-06-22 22:23:17 +02:00
|
|
|
- [Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`,
|
|
|
|
|
`From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>`
|
|
|
|
|
for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for
|
|
|
|
|
`Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>`
|
|
|
|
|
for `PathBuf`.][50170]
|
2018-06-23 11:45:46 +02:00
|
|
|
- [Implemented `Shl` and `Shr` for `Wrapping<u128>`
|
|
|
|
|
and `Wrapping<i128>`.][50465]
|
2018-06-22 22:23:17 +02:00
|
|
|
- [`DirEntry::metadata` now uses `fstatat` instead of `lstat` when
|
|
|
|
|
possible.][51050] This can provide up to a 40% speed increase.
|
|
|
|
|
- [Improved error messages when using `format!`.][50610]

- [Rust will consider trait objects with duplicated constraints to be the same

type as without the duplicated constraint.][51276] For example the below code will

Security Notes
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
- rustdoc would execute plugins in the /tmp/rustdoc/plugins directory
|
|
|
|
|
when running, which enabled executing code as some other user on a
|
|
|
|
|
given machine. This release fixes that vulnerability; you can read
|
|
|
|
|
more about this on the [blog][rustdoc-sec]. The associated CVE is [CVE-2018-1000622].
|
|
|

|
==========================

|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
- [Removed 'proc' from the reserved keywords list.][49699] This allows `proc` to
|
2018-07-30 17:41:19 +02:00
|
|
|
be used as an identifier.
|
2018-06-01 00:32:20 +02:00
|
|
|
- [The dyn syntax is now available.][49968] This syntax is equivalent to the
|
|
|
|
|
bare `Trait` syntax, and should make it clearer when being used in tandem with
|
2018-10-23 13:53:48 +02:00
|
|
|
`impl Trait` because it is equivalent to the following syntax:
|
2018-06-01 00:32:20 +02:00
|
|
|
`&Trait == &dyn Trait`, `&mut Trait == &mut dyn Trait`, and
|
|
|
|
|
`Box<Trait> == Box<dyn Trait>`.
|
|
|
|
|
- [Attributes on generic parameters such as types and lifetimes are
|
|
|
|
|
now stable.][48851] e.g.
|
|
|
|
|
`fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}`
|
|
|
|
|
- [The `#[must_use]` attribute can now also be used on functions as well as
|
|
|
|
|
types.][48925] It provides a lint that by default warns users when the
|
|
|
|
|
value returned by a function has not been used.
|
|

|
|

|
|
|
|
Compiler
|
|
|
|
|
--------
|
2018-08-01 17:24:18 +02:00
|
|
|
- [Added the `armv5te-unknown-linux-musleabi` target.][50423]
|
2018-06-01 00:32:20 +02:00
|
|
|
|
|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
- [SIMD (Single Instruction Multiple Data) on x86/x86_64 is now stable.][49664]
|
|
|
|
|
This includes [`arch::x86`] & [`arch::x86_64`] modules which contain
|
|
|
|
|
SIMD intrinsics, a new macro called `is_x86_feature_detected!`, the
|
|
|
|
|
`#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to
|
|
|
|
|
the `cfg` attribute.
|
|
|
|
|
- [A lot of methods for `[u8]`, `f32`, and `f64` previously only available in
|
|
|
|
|
std are now available in core.][49896]
|
|
|
|
|
- [The generic `Rhs` type parameter on `ops::{Shl, ShlAssign, Shr}` now defaults
|
|
|
|
|
to `Self`.][49630]
|
|
|
|
|
- [`std::str::replace` now has the `#[must_use]` attribute][50177] to clarify
|
|
|
|
|
that the operation isn't done in place.
|
|
|
|
|
- [`Clone::clone`, `Iterator::collect`, and `ToOwned::to_owned` now have
|
|
|
|
|
the `#[must_use]` attribute][49533] to warn about unused potentially
|
|
|
|
|
expensive allocations.

|

Cargo
|
|
|
|
|
-----
|
|
|
|
|
- [`cargo-metadata` now includes `authors`, `categories`, `keywords`,
|
|
|
|
|
`readme`, and `repository` fields.][cargo/5386]
|
2018-07-02 19:47:51 +02:00
|
|
|
- [`cargo-metadata` now includes a package's `metadata` table.][cargo/5360]
|
2018-06-01 00:32:20 +02:00
|
|
|
- [Added the `--target-dir` optional argument.][cargo/5393] This allows you to specify
|
|
|
|
|
a different directory than `target` for placing compilation artifacts.
|
|
|
|
|
- [Cargo will be adding automatic target inference for binaries, benchmarks,
|
|
|
|
|
examples, and tests in the Rust 2018 edition.][cargo/5335] If your project specifies
|
2018-10-23 13:53:48 +02:00
|
|
|
specific targets, e.g. using `[[bin]]`, and have other binaries in locations
|
2018-06-01 00:32:20 +02:00
|
|
|
where cargo would infer a binary, Cargo will produce a warning. You can
|
2018-10-23 13:53:48 +02:00
|
|
|
disable this feature ahead of time by setting any of the following to false:
|
|
|
|
|
`autobins`, `autobenches`, `autoexamples`, `autotests`.
|
2018-06-01 00:32:20 +02:00
|
|
|
- [Cargo will now cache compiler information.][cargo/5359] This can be disabled by
|
|
|
|
|
setting `CARGO_CACHE_RUSTC_INFO=0` in your environment.
|
|
|
|
|

|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
- [Added “The Rustc book” into the official documentation.][49707]
|
|
|
|
|
[“The Rustc book”] documents and teaches how to use the rustc compiler.
|
|
|
|
|
- [All books available on `doc.rust-lang.org` are now searchable.][49623]
|
|
|
|
|
|
|
|
|
|
Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
- [Calling a `CharExt` or `StrExt` method directly on core will no longer
|
|
|
|
|
work.][49896] e.g. `::core::prelude::v1::StrExt::is_empty("")` will not
|
|
|
|
|
compile, `"".is_empty()` will still compile.
|
|
|
|
|
- [`Debug` output on `atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize}`
|
2018-10-23 13:53:48 +02:00
|
|
|
will only print the inner type.][48553] E.g.
|
|
|
|
|
`print!("{:?}", AtomicBool::new(true))` will print `true`,
|
2018-06-01 00:32:20 +02:00
|
|
|
not `AtomicBool(true)`.
|
|
|
|
|
- [The maximum number for `repr(align(N))` is now 2²⁹.][50378] Previously you
|
|
|
|
|
could enter higher numbers but they were not supported by LLVM. Up to 512MB
|
|
|
|
|
alignment should cover all use cases.
|
2018-09-09 00:36:17 +02:00
|
|
|
- The `.description()` method on the `std::error::Error` trait
|
|
|
|
|
[has been soft-deprecated][50163]. It is no longer required to implement it.

|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
- [Closures now implement `Copy` and/or `Clone` if all captured variables
|
|
|
|
|
implement either or both traits.][49299]
|
|
|
|
|
- [The inclusive range syntax e.g. `for x in 0..=10` is now stable.][47813]
|
2018-10-23 13:53:48 +02:00
|
|
|
- [The `'_` lifetime is now stable. The underscore lifetime can be used anywhere a
|
2018-05-01 14:49:31 +02:00
|
|
|
lifetime can be elided.][49458]
|
2018-05-09 12:06:20 +02:00
|
|
|
- [`impl Trait` is now stable allowing you to have abstract types in returns
|
2018-10-23 13:53:48 +02:00
|
|
|
or in function parameters.][49255] E.g. `fn foo() -> impl Iterator<Item=u8>` or
|
2018-05-01 14:49:31 +02:00
|
|
|
`fn open(path: impl AsRef<Path>)`.
|
|
|
|
|
- [Pattern matching will now automatically apply dereferences.][49394]
|
|
|
|
|
- [128-bit integers in the form of `u128` and `i128` are now stable.][49101]
|
|
|
|
|
- [`main` can now return `Result<(), E: Debug>`][49162] in addition to `()`.
|
2018-05-07 12:37:36 +02:00
|
|
|
- [A lot of operations are now available in a const context.][46882] E.g. You
|
2018-05-09 12:06:20 +02:00
|
|
|
can now index into constant arrays, reference and dereference into constants,
|
2018-10-23 13:53:48 +02:00
|
|
|
and use tuple struct constructors.
|
|
|
|
|
- [Fixed entry slice patterns are now stable.][48516] E.g.
|
2018-05-01 14:49:31 +02:00
|
|
|
```rust
|
|
|
|
|
let points = [1, 2, 3, 4];
|
|
|
|
|
match points {
|
|
|
|
|
[1, 2, 3, 4] => println!("All points were sequential."),
|
|
|
|
|
_ => println!("Not all points were sequential."),
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Compiler
|
|
|
|
|
--------
|
|
|
|
|
- [LLD is now used as the default linker for `wasm32-unknown-unknown`.][48125]
|
|
|
|
|
- [Fixed exponential projection complexity on nested types.][48296]
|
|
|
|
|
This can provide up to a ~12% reduction in compile times for certain crates.
|
|
|
|
|
- [Added the `--remap-path-prefix` option to rustc.][48359] Allowing you
|
|
|
|
|
to remap path prefixes outputted by the compiler.
|
|
|
|
|
- [Added `powerpc-unknown-netbsd` target.][48281]
|
|
|
|
|
|
|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
- [Implemented `From<u16> for usize` & `From<{u8, i16}> for isize`.][49305]
|
|
|
|
|
- [Added hexadecimal formatting for integers with fmt::Debug][48978]
|
|
|
|
|
e.g. `assert!(format!("{:02x?}", b"Foo\0") == "[46, 6f, 6f, 00]")`
|
|
|
|
|
- [Implemented `Default, Hash` for `cmp::Reverse`.][48628]
|
|
|
|
|
- [Optimized `str::repeat` being 8x faster in large cases.][48657]
|
|
|
|
|
- [`ascii::escape_default` is now available in libcore.][48735]
|
|
|
|
|
- [Trailing commas are now supported in std and core macros.][48056]
|
|
|
|
|
- [Implemented `Copy, Clone` for `cmp::Reverse`][47379]
|
|
|
|
|
- [Implemented `Clone` for `char::{ToLowercase, ToUppercase}`.][48629]

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
- [aliasing a `Fn` trait as `dyn` no longer works.][48481] E.g. the following
|
|
|
|
|
syntax is now invalid.
|
|
|
|
|
```
|
|
|
|
|
use std::ops::Fn as dyn;
|
|
|
|
|
fn g(_: Box<dyn(std::fmt::Debug)>) {}
|
|
|
|
|
```
|
|
|
|
|
- [The result of dereferences are no longer promoted to `'static`.][47408]
|
|
|
|
|
e.g.
|
|
|
|
|
```rust
|
|
|
|
|
fn main() {
|
|
|
|
|
const PAIR: &(i32, i32) = &(0, 1);
|
|
|
|
|
let _reversed_pair: &'static _ = &(PAIR.1, PAIR.0); // Doesn't work
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
- [Deprecate `AsciiExt` trait in favor of inherent methods.][49109]
|
|
|
|
|
- [`".e0"` will now no longer parse as `0.0` and will instead cause
|
|
|
|
|
an error.][48235]
|
|
|
|
|
- [Removed hoedown from rustdoc.][48274]
|
2018-05-09 12:06:20 +02:00
|
|
|
- [Bounds on higher-kinded lifetimes a hard error.][48326]

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
- [Deprecated `net::lookup_host`.][47510]
|
|
|
|

|
2018-02-20 20:55:14 +01:00
|
|
|
around indexing operations (see [#47349][47349]). This has been fixed (which also
|
|
|
|
|
enabled some correct code that used to cause errors (e.g. [#33903][33903] and [#46095][46095]).
|
2018-02-20 17:34:49 +01:00
|
|
|

Cargo
|
|
|
|
|
-----
|
|
|
|
|
- [Cargo API token location moved from `~/.cargo/config` to
|
2017-08-22 05:29:05 +02:00
|
|
|
`~/.cargo/credentials`.][cargo/3978]
|
2017-08-09 17:19:54 +02:00
|
|
|
- [Cargo will now build `main.rs` binaries that are in sub-directories of
|
|
|
|
|
`src/bin`.][cargo/4214] ie. Having `src/bin/server/main.rs` and
|
|
|
|
|
`src/bin/client/main.rs` generates `target/debug/server` and `target/debug/client`
|
2017-08-03 15:56:25 +02:00
|
|
|
- [You can now specify version of a binary when installed through
|
|
|
|
|
`cargo install` using `--vers`.][cargo/4229]
|
|
|
|
|
- [Added `--no-fail-fast` flag to cargo to run all benchmarks regardless of
|
|
|
|
|
failure.][cargo/4248]
|
|
|
|
|
- [Changed the convention around which file is the crate root.][cargo/4259]
|
|
|
|
|
- [The `include`/`exclude` property in `Cargo.toml` now accepts gitignore paths
|
|
|
|
|
instead of glob patterns][cargo/4270]. Glob patterns are now deprecated.

|
|
-------------------
|
|
|
|
|
|
|
|
|
|
- [Functions with `'static` in their return types will now not be as usable as

|
|
if they were using lifetime parameters instead.][42417]
|
2017-08-04 14:40:05 +02:00
|
|
|
- [The reimplementation of `{f32, f64}::is_sign_{negative, positive}` now
|
2017-09-11 00:24:10 +02:00
|
|
|
takes the sign of NaN into account where previously didn't.][42430]

Version 1.19.0 (2017-07-20)
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
- [Numeric fields can now be used for creating tuple structs.][41145] [RFC 1506]
|
|
|
|
|
For example `struct Point(u32, u32); let x = Point { 0: 7, 1: 0 };`.
|
|
|
|
|
- [Macro recursion limit increased to 1024 from 64.][41676]
|
|
|
|
|
- [Added lint for detecting unused macros.][41907]
|
|
|
|
|
- [`loop` can now return a value with `break`.][42016] [RFC 1624]
|
|
|
|
|
For example: `let x = loop { break 7; };`
|
|
|
|
|
- [C compatible `union`s are now available.][42068] [RFC 1444] They can only
|
|
|
|
|
contain `Copy` types and cannot have a `Drop` implementation.
|
|
|
|
|
Example: `union Foo { bar: u8, baz: usize }`
|
|
|
|
|
- [Non capturing closures can now be coerced into `fn`s,][42162] [RFC 1558]
|
|
|
|
|
Example: `let foo: fn(u8) -> u8 = |v: u8| { v };`
|
|
|
|
|
|
|
|
|
|
Compiler
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
- [Add support for bootstrapping the Rust compiler toolchain on Android.][41370]
|
|
|
|
|
- [Change `arm-linux-androideabi` to correspond to the `armeabi`
|
|
|
|
|
official ABI.][41656] If you wish to continue targeting the `armeabi-v7a` ABI
|
|
|
|
|
you should use `--target armv7-linux-androideabi`.
|
|
|
|
|
- [Fixed ICE when removing a source file between compilation sessions.][41873]
|
|
|
|
|
- [Minor optimisation of string operations.][42037]
|
|
|
|
|
- [Compiler error message is now `aborting due to previous error(s)` instead of
|
|
|
|
|
`aborting due to N previous errors`][42150] This was previously inaccurate and
|
|
|
|
|
would only count certain kinds of errors.
|
|
|
|
|
- [The compiler now supports Visual Studio 2017][42225]
|
|
|
|
|
- [The compiler is now built against LLVM 4.0.1 by default][42948]
|
|
|
|
|
- [Added a lot][42264] of [new error codes][42302]
|
|
|
|
|
- [Added `target-feature=+crt-static` option][37406] [RFC 1721] Which allows
|
|
|
|
|
libraries with C Run-time Libraries(CRT) to be statically linked.
|
|
|
|
|
- [Fixed various ARM codegen bugs][42740]
|
|
|
|
|
|
|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
- [`String` now implements `FromIterator<Cow<'a, str>>` and
|
|
|
|
|
`Extend<Cow<'a, str>>`][41449]
|
|
|
|
|
- [`Vec` now implements `From<&mut [T]>`][41530]
|
|
|
|
|
- [`Box<[u8]>` now implements `From<Box<str>>`][41258]
|
|
|
|
|
- [`SplitWhitespace` now implements `Clone`][41659]
|
|
|
|
|
- [`[u8]::reverse` is now 5x faster and `[u16]::reverse` is now
|
|
|
|
|
1.5x faster][41764]
|
|
|
|
|
- [`eprint!` and `eprintln!` macros added to prelude.][41192] Same as the `print!`
|
|
|
|
|
macros, but for printing to stderr.
|
|
|
|
|
|
|
|
|
|
Stabilized APIs
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
- [`OsString::shrink_to_fit`]
|
|
|
|
|
- [`cmp::Reverse`]
|
|
|
|
|
- [`Command::envs`]
|
|
|
|
|
- [`thread::ThreadId`]
|
|
|
|
|
|
|
|
|
|
Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
- [Build scripts can now add environment variables to the environment
|
|
|
|
|
the crate is being compiled in.
|
|
|
|
|
Example: `println!("cargo:rustc-env=FOO=bar");`][cargo/3929]
|
|
|
|
|
- [Subcommands now replace the current process rather than spawning a new
|
|
|
|
|
child process][cargo/3970]
|
|
|
|
|
- [Workspace members can now accept glob file patterns][cargo/3979]
|
|
|
|
|
- [Added `--all` flag to the `cargo bench` subcommand to run benchmarks of all
|
|
|
|
|
the members in a given workspace.][cargo/3988]
|
|
|
|
|
- [Updated `libssh2-sys` to 0.2.6][cargo/4008]
|
|
|
|
|
- [Target directory path is now in the cargo metadata][cargo/4022]
|
|
|
|
|
- [Cargo no longer checks out a local working directory for the
|
|
|
|
|
crates.io index][cargo/4026] This should provide smaller file size for the
|
|
|
|
|
registry, and improve cloning times, especially on Windows machines.
|
|
|
|
|
- [Added an `--exclude` option for excluding certain packages when using the
|
|
|
|
|
`--all` option][cargo/4031]
|
|
|
|
|
- [Cargo will now automatically retry when receiving a 5xx error
|
|
|
|
|
from crates.io][cargo/4032]
|
|
|
|
|
- [The `--features` option now accepts multiple comma or space
|
|
|
|
|
delimited values.][cargo/4084]
|
|
|
|
|
- [Added support for custom target specific runners][cargo/3954]
|
|
|
|
|
|
|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
- [Added `rust-windbg.cmd`][39983] for loading rust `.natvis` files in the
|
|
|
|
|
Windows Debugger.
|
|
|
|
|
- [Rust will now release XZ compressed packages][rust-installer/57]
|
|
|
|
|
- [rustup will now prefer to download rust packages with
|
|
|
|
|
XZ compression][rustup/1100] over GZip packages.
|
|
|
|
|
- [Added the ability to escape `#` in rust documentation][41785] By adding
|
|
|
|
|
additional `#`'s ie. `##` is now `#`
|
|
|
|
|
|
|
|
|
|
Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
- [`MutexGuard<T>` may only be `Sync` if `T` is `Sync`.][41624]
|
|
|
|
|
- [`-Z` flags are now no longer allowed to be used on the stable
|
|
|
|
|
compiler.][41751] This has been a warning for a year previous to this.
|
|
|
|
|
- [As a result of the `-Z` flag change, the `cargo-check` plugin no
|
|
|
|
|
longer works][42844]. Users should migrate to the built-in `check`
|
|
|
|
|
command, which has been available since 1.16.
|
|

|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
- [Stabilize pub(restricted)][40556] `pub` can now accept a module path to
|
|
|
|
|
make the item visible to just that module tree. Also accepts the keyword
|
|
|
|
|
`crate` to make something public to the whole crate but not users of the
|
|
|
|
|
library. Example: `pub(crate) mod utils;`. [RFC 1422].
|
|
|
|
|
- [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the
|
|
|
|
|
`/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665].
|
|
|
|
|
- [Refactor of trait object type parsing][40043] Now `ty` in macros can accept
|
|
|
|
|
types like `Write + Send`, trailing `+` are now supported in trait objects,
|
|
|
|
|
and better error reporting for trait objects starting with `?Sized`.
|
|
|
|
|
- [0e+10 is now a valid floating point literal][40589]
|
|
|
|
|
- [Now warns if you bind a lifetime parameter to 'static][40734]
|
|
|
|
|
- [Tuples, Enum variant fields, and structs with no `repr` attribute or with
|
|
|
|
|
`#[repr(Rust)]` are reordered to minimize padding and produce a smaller
|
|
|
|
|
representation in some cases.][40377]

|
|
|
|

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
- [Changes to how the `0` flag works in format!][40241] Padding zeroes are now
|
|
|
|
|
always placed after the sign if it exists and before the digits. With the `#`
|
|
|
|
|
flag the zeroes are placed after the prefix and before the digits.
|
|
|
|
|
- [Due to the struct field optimisation][40377], using `transmute` on structs
|
|
|
|
|
that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has
|
|
|
|
|
always been undefined behavior, but is now more likely to break in practice.
|
|
|
|
|
- [The refactor of trait object type parsing][40043] fixed a bug where `+` was
|
|
|
|
|
receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as
|
|
|
|
|
`&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send`
|
|
|
|
|
- [Overlapping inherent `impl`s are now a hard error][40728]
|
|
|
|
|
- [`PartialOrd` and `Ord` must agree on the ordering.][41270]
|
|
|
|
|
- [`rustc main.rs -o out --emit=asm,llvm-ir`][41085] Now will output
|
|
|
|
|
`out.asm` and `out.ll` instead of only one of the filetypes.
|
|
|
|
|
- [ calling a function that returns `Self` will no longer work][41805] when
|
|
|
|
|
the size of `Self` cannot be statically determined.
|
|
|
|
|
- [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805]
|
|
|
|
|
this has caused a few regressions namely:
|
|
|
|
|
|
|
|
|
|
- Changed the link order of local static/dynamic libraries (respecting the
|
|
|
|
|
order on given rather than having the compiler reorder).
|
|
|
|
|
- Changed how MinGW is linked, native code linked to dynamic libraries
|
|
|
|
|
may require manually linking to the gcc support library (for the native
|
|
|
|
|
code itself)

Version 1.17.0 (2017-04-27)
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* [The lifetime of statics and consts defaults to `'static`][39265]. [RFC 1623]
|
|
|
|
|
* [Fields of structs may be initialized without duplicating the field/variable
|
|
|
|
|
names][39761]. [RFC 1682]
|
|
|
|
|
* [`Self` may be included in the `where` clause of `impls`][38864]. [RFC 1647]
|
|
|
|
|
* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
|
|
|
|
|
there is no subtyping between `T` and `U` when `T: Unsize<U>`. For example,
|
|
|
|
|
coercing `&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to
|
|
|
|
|
`'b`. Soundness fix.
|
|
|
|
|
* [Values passed to the indexing operator, `[]`, automatically coerce][40166]
|
|
|
|
|
* [Static variables may contain references to other statics][40027]
|
|
|
|
|
|
|
|
|
|
Compiler
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* [Exit quickly on only `--emit dep-info`][40336]
|
|
|
|
|
* [Make `-C relocation-model` more correctly determine whether the linker
|
|
|
|
|
creates a position-independent executable][40245]
|
|
|
|
|
* [Add `-C overflow-checks` to directly control whether integer overflow
|
|
|
|
|
panics][40037]
|
|
|
|
|
* [The rustc type checker now checks items on demand instead of in a single
|
|
|
|
|
in-order pass][40008]. This is mostly an internal refactoring in support of
|
|
|
|
|
future work, including incremental type checking, but also resolves [RFC
|
|
|
|
|
1647], allowing `Self` to appear in `impl` `where` clauses.
|
|
|
|
|
* [Optimize vtable loads][39995]
|
|
|
|
|
* [Turn off vectorization for Emscripten targets][39990]
|
|
|
|
|
* [Provide suggestions for unknown macros imported with `use`][39953]
|
|
|
|
|
* [Fix ICEs in path resolution][39939]
|
|
|
|
|
* [Strip exception handling code on Emscripten when `panic=abort`][39193]
|
|
|
|
|
* [Add clearer error message using `&str + &str`][39116]

|
|
----
|
|

|
|
|
|

|
|
`rustbook`][39633]
|

|
|
|
|
|
* [Improve the style of the sidebar in rustdoc output][40265]
|
|

|
|
|
|
* [Fix MSP430 breakage due to `i128`][40257]
|
|
|
|
|
* [Preliminary Solaris/SPARCv9 support][39903]
|
|
|
|
|
* [`rustc` is linked statically on Windows MSVC targets][39837], allowing it to
|
|
|
|
|
run without installing the MSVC runtime.
|
|
|
|
|
* [`rustdoc --test` includes file names in test names][39788]
|
|
|
|
|
* This release includes builds of `std` for `sparc64-unknown-linux-gnu`,

|
|
|
|
|
* [This release no longer includes the old makefile build system][39431]. Rust
|
|

|
is built with a custom build system, written in Rust, and with Cargo.

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* [Rust 1.17 does not correctly detect the MSVC 2017 linker][38584]. As a
|
|
|
|
|
workaround, either use MSVC 2015 or run vcvars.bat.
|
|
|
|
|
* [When coercing to an unsized type lifetimes must be equal][40319]. That is,
|
|
|
|
|
disallow subtyping between `T` and `U` when `T: Unsize<U>`, e.g. coercing
|
|
|
|
|
`&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to `'b`. Soundness
|
|
|
|
|
fix.
|
|
|
|
|
* [`format!` and `Display::to_string` panic if an underlying formatting
|
|
|
|
|
implementation returns an error][40117]. Previously the error was silently
|
|
|
|
|
ignored. It is incorrect for `write_fmt` to return an error when writing
|
|
|
|
|
to a string.
|
|
|
|
|
* [In-tree crates are verified to be unstable][39851]. Previously, some minor
|
|
|
|
|
crates were marked stable and could be accessed from the stable toolchain.
|
|
|
|
|
* [Rust git source no longer includes vendored crates][39728]. Those that need
|
|
|
|
|
to build with vendored crates should build from release tarballs.
|
|
|
|
|
* [Fix inert attributes from `proc_macro_derives`][39572]
|
|
|
|
|
* [During crate resolution, rustc prefers a crate in the sysroot if two crates
|
|
|
|
|
are otherwise identical][39518]. Unlikely to be encountered outside the Rust
|
|
|
|
|
build system.
|
|
|
|
|
* [Fixed bugs around how type inference interacts with dead-code][39485]. The
|
|
|
|
|
existing code generally ignores the type of dead-code unless a type-hint is
|
|
|
|
|
provided; this can cause surprising inference interactions particularly around
|
|
|
|
|
defaulting. The new code uniformly ignores the result type of dead-code.
|
|
|
|
|
* [Tuple-struct constructors with private fields are no longer visible][38932]
|
|
|
|
|
* [Lifetime parameters that do not appear in the arguments are now considered
|
|
|
|
|
early-bound][38897], resolving a soundness bug (#[32330]). The
|
|
|
|
|
`hr_lifetime_in_assoc_type` future-compatibility lint has been in effect since
|
|
|
|
|
April of 2016.
|
|
|
|
|
* [rustdoc: fix doctests with non-feature crate attributes][38161]
|
|
|
|
|
* [Make transmuting from fn item types to pointer-sized types a hard
|
|
|
|
|
error][34198]

Version 1.16.0 (2017-03-16)
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* [The compiler's `dead_code` lint now accounts for type aliases][38051].
|
|
|
|
|
* [Uninhabitable enums (those without any variants) no longer permit wildcard
|
|
|
|
|
match patterns][38069]
|
|
|
|
|
* [Clean up semantics of `self` in an import list][38313]
|
|
|
|
|
* [`Self` may appear in `impl` headers][38920]
|
|
|
|
|
* [`Self` may appear in struct expressions][39282]
|
|
|
|
|
|
|
|
|
|
Compiler
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* [`rustc` now supports `--emit=metadata`, which causes rustc to emit
|
|
|
|
|
a `.rmeta` file containing only crate metadata][38571]. This can be
|
|
|
|
|
used by tools like the Rust Language Service to perform
|
|
|
|
|
metadata-only builds.
|
|
|
|
|
* [Levenshtein based typo suggestions now work in most places, while
|
|
|
|
|
previously they worked only for fields and sometimes for local
|
|
|
|
|
variables][38927]. Together with the overhaul of "no
|
|
|
|
|
resolution"/"unexpected resolution" errors (#[38154]) they result in
|
|
|
|
|
large and systematic improvement in resolution diagnostics.
|
|
|
|
|
* [Fix `transmute::<T, U>` where `T` requires a bigger alignment than
|
|
|
|
|
`U`][38670]
|
|
|
|
|
* [rustc: use -Xlinker when specifying an rpath with ',' in it][38798]
|
|
|
|
|
* [`rustc` no longer attempts to provide "consider using an explicit
|
|
|
|
|
lifetime" suggestions][37057]. They were inaccurate.
|
|

Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* [`[T]::binary_search` and `[T]::binary_search_by_key` now take
|
|
|
|
|
their argument by `Borrow` parameter][37761]
|
|

|
* [Use more specific panic message for `&str` slicing errors][38066]
|
|
|
|
|
* [`TcpListener::set_only_v6` is deprecated][38304]. This
|
|
|
|
|
functionality cannot be achieved in std currently.
|
|
|
|
|
* [`writeln!`, like `println!`, now accepts a form with no string
|

Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* [The `cargo check` command does a type check of a project without
|
|
|
|
|
building it][cargo/3296]
|
|
|
|
|
* [crates.io will display CI badges from Travis and AppVeyor, if

|
|
|
|
specified in Cargo.toml][cargo/3546]

|
|
|
|
|
* [Compilation profiles accept integer values for `debug`, in addition
|
|
|
|
|

|
`-C debuginfo`][cargo/3534]
|
|
|
|
|
* [Implement `cargo --version --verbose`][cargo/3604]

Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* [`rustdoc` has a `--sysroot` argument that, like `rustc`, specifies
|
|
|
|
|
the path to the Rust implementation][38589]
|
|
|
|
|
* [The `armv7-linux-androideabi` target no longer enables NEON

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* [Uninhabitable enums (those without any variants) no longer permit wildcard
|
|
|
|
|
match patterns][38069]
|
|
|
|
|
* In this release, references to uninhabited types can not be
|
|
|
|
|
pattern-matched. This was accidentally allowed in 1.15.
|
|
|
|
|
* [The compiler's `dead_code` lint now accounts for type aliases][38051].
|
|
|
|
|
* [Ctrl-Z returns from `Stdin.read()` when reading from the console on
|
|
|
|
|
Windows][38274]
|
|
|
|
|
* [Clean up semantics of `self` in an import list][38313]
|
2017-08-20 21:49:36 +02:00
|
|
|
* Reimplemented lifetime elision. This change was almost entirely compatible
|
|
|
|
|
with existing code, but it did close a number of small bugs and loopholes,
|
|
|
|
|
as well as being more accepting in some other [cases][41105].

Version 1.15.0 (2017-02-02)
|
|
|
|
|
===========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* Basic procedural macros allowing custom `#[derive]`, aka "macros 1.1", are
|
|
|
|
|
stable. This allows popular code-generating crates like Serde and Diesel to
|
|
|
|
|
work ergonomically. [RFC 1681].
|
|
|
|
|
* [Tuple structs may be empty. Unary and empty tuple structs may be instantiated
|
|
|
|
|
with curly braces][36868]. Part of [RFC 1506].
|
|
|
|
|
* [A number of minor changes to name resolution have been activated][37127].
|
|
|
|
|
They add up to more consistent semantics, allowing for future evolution of
|
|
|
|
|
Rust macros. Specified in [RFC 1560], see its section on ["changes"] for
|
|
|
|
|
details of what is different. The breaking changes here have been transitioned
|
|
|
|
|
through the [`legacy_imports`] lint since 1.14, with no known regressions.
|
|
|
|
|
* [In `macro_rules`, `path` fragments can now be parsed as type parameter
|
|
|
|
|
bounds][38279]
|
|
|
|
|
* [`?Sized` can be used in `where` clauses][37791]
|
|
|
|
|
* [There is now a limit on the size of monomorphized types and it can be
|
|
|
|
|
modified with the `#![type_size_limit]` crate attribute, similarly to
|
|
|
|
|
the `#![recursion_limit]` attribute][37789]
|
|
|
|
|
|
|
|
|
|
Compiler
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* [On Windows, the compiler will apply dllimport attributes when linking to
|
|
|
|
|
extern functions][37973]. Additional attributes and flags can control which
|
|
|
|
|
library kind is linked and its name. [RFC 1717].
|
|
|
|
|
* [Rust-ABI symbols are no longer exported from cdylibs][38117]
|
|
|
|
|
* [The `--test` flag works with procedural macro crates][38107]
|
|
|
|
|
* [Fix `extern "aapcs" fn` ABI][37814]
|
|
|
|
|
* [The `-C no-stack-check` flag is deprecated][37636]. It does nothing.
|
|
|
|
|
* [The `format!` expander recognizes incorrect `printf` and shell-style
|
|
|
|
|
formatting directives and suggests the correct format][37613].
|
|
|
|
|
* [Only report one error for all unused imports in an import list][37456]
|
|
|
|
|
|
|
|
|
|
Compiler Performance
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
* [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705]
|
|
|
|
|
* [Avoid more unnecessary `mk_ty` calls in `Ty::super_fold_with`][37979]
|
|
|
|
|
* [Don't clone in `UnificationTable::probe`][37848]
|
|
|
|
|
* [Remove `scope_auxiliary` to cut RSS by 10%][37764]
|
|
|
|
|
* [Use small vectors in type walker][37760]
|
|
|
|
|
* [Macro expansion performance was improved][37701]
|
|
|
|
|
* [Change `HirVec<P<T>>` to `HirVec<T>` in `hir::Expr`][37642]
|
|
|
|
|
* [Replace FNV with a faster hash function][37229]

Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* [The standard sorting algorithm has been rewritten for dramatic performance
|
|
|
|
|
improvements][38192]. It is a hybrid merge sort, drawing influences from
|
|
|
|
|
Timsort. Previously it was a naive merge sort.
|
|
|
|
|
* [`Iterator::nth` no longer has a `Sized` bound][38134]
|
|
|
|
|
* [`Extend<&T>` is specialized for `Vec` where `T: Copy`][38182] to improve
|
|
|
|
|
performance.
|
|
|
|
|
* [`chars().count()` is much faster][37888] and so are [`chars().last()`
|
|
|
|
|
and `char_indices().last()`][37882]
|
|
|
|
|
* [Fix ARM Objective-C ABI in `std::env::args`][38146]
|
|
|
|
|
* [Chinese characters display correctly in `fmt::Debug`][37855]
|
|
|
|
|
* [Derive `Default` for `Duration`][37699]
|
|
|
|
|
* [Support creation of anonymous pipes on WinXP/2k][37677]
|
|
|
|
|
* [`mpsc::RecvTimeoutError` implements `Error`][37527]
|
|
|
|
|
* [Don't pass overlapped handles to processes][38835]
|
|
|
|
|
|
|
|
|
|
Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* [In this release, Cargo build scripts no longer have access to the `OUT_DIR`
|
|
|
|
|
environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They
|
|
|
|
|
should instead check the variable at runtime with `std::env`. That the value
|
|
|
|
|
was set at build time was a bug, and incorrect when cross-compiling. This
|
|
|
|
|
change is known to cause breakage.
|
|
|
|
|
* [Add `--all` flag to `cargo test`][cargo/3221]
|
|
|
|
|
* [Compile statically against the MSVC CRT][cargo/3363]
|
|
|
|
|
* [Mix feature flags into fingerprint/metadata shorthash][cargo/3102]
|
|
|
|
|
* [Link OpenSSL statically on OSX][cargo/3311]
|
|
|
|
|
* [Apply new fingerprinting to build dir outputs][cargo/3310]
|
|
|
|
|
* [Test for bad path overrides with summaries][cargo/3336]
|
|
|
|
|
* [Require `cargo install --vers` to take a semver version][cargo/3338]
|
|
|
|
|
* [Fix retrying crate downloads for network errors][cargo/3348]
|
|
|
|
|
* [Implement string lookup for `build.rustflags` config key][cargo/3356]
|
|
|
|
|
* [Emit more info on --message-format=json][cargo/3319]
|
|
|
|
|
* [Assume `build.rs` in the same directory as `Cargo.toml` is a build script][cargo/3361]
|
|
|
|
|
* [Don't ignore errors in workspace manifest][cargo/3409]
|
|
|
|
|
* [Fix `--message-format JSON` when rustc emits non-JSON warnings][cargo/3410]
|
|
|
|
|
|
|
|
|
|
Tooling
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
* [Test runners (binaries built with `--test`) now support a `--list` argument
|
|
|
|
|
that lists the tests it contains][38185]
|
|
|
|
|
* [Test runners now support a `--exact` argument that makes the test filter
|
|
|
|
|
match exactly, instead of matching only a substring of the test name][38181]
|
|
|
|
|
* [rustdoc supports a `--playground-url` flag][37763]
|
|
|
|
|
* [rustdoc provides more details about `#[should_panic]` errors][37749]
|
|
|
|
|
|
|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* [The Rust build system is now written in Rust][37817]. The Makefiles may
|
|
|
|
|
continue to be used in this release by passing `--disable-rustbuild` to the
|
|
|
|
|
configure script, but they will be deleted soon. Note that the new build
|
|
|
|
|
system uses a different on-disk layout that will likely affect any scripts
|
|
|
|
|
building Rust.
|
|
|
|
|
* [Rust supports i686-unknown-openbsd][38086]. Tier 3 support. No testing or
|
|
|
|
|
releases.
|
|
|
|
|
* [Rust supports the MSP430][37627]. Tier 3 support. No testing or releases.
|
|
|
|
|
* [Rust supports the ARMv5TE architecture][37615]. Tier 3 support. No testing or
|
|
|
|
|
releases.

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* [A number of minor changes to name resolution have been activated][37127].
|
|
|
|
|
They add up to more consistent semantics, allowing for future evolution of
|
|
|
|
|
Rust macros. Specified in [RFC 1560], see its section on ["changes"] for
|
|
|
|
|
details of what is different. The breaking changes here have been transitioned
|
|
|
|
|
through the [`legacy_imports`] lint since 1.14, with no known regressions.
|
|
|
|
|
* [In this release, Cargo build scripts no longer have access to the `OUT_DIR`
|
|
|
|
|
environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They
|
|

|
|
|
|
|
was set at build time was a bug, and incorrect when cross-compiling. This
|
|
|
|
|
change is known to cause breakage.
|
|
|
|
|
* [Higher-ranked lifetimes are no longer allowed to appear _only_ in associated
|
|
|
|
|
types][33685]. The [`hr_lifetime_in_assoc_type` lint] has been a warning since
|
|
|
|
|
1.10 and is now an error by default. It will become a hard error in the near
|
|
|
|
|
future.
|
|
|
|
|
* [The semantics relating modules to file system directories are changing in
|
|
|
|
|
minor ways][37602]. This is captured in the new `legacy_directory_ownership`
|
|
|
|
|
lint, which is a warning in this release, and will become a hard error in the
|
|
|
|
|
future.
|
|
|
|
|
* [Rust-ABI symbols are no longer exported from cdylibs][38117]
|
|
|
|
|
* [Once `Peekable` peeks a `None` it will return that `None` without re-querying
|
|
|
|
|
the underlying iterator][37834]

|
|
|
|
|
S390x. These are [tier 2] platforms and may have major defects. Follow the
|
|
|
|
|
instructions on the website to install, or add the targets to an existing
|
|
|
|

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* [A number of forward-compatibility lints used by the compiler
|
|
|
|
|
to gradually introduce language changes have been converted
|
|
|
|
|
to deny by default][36894]:
|
|
|
|
|
- ["use of inaccessible extern crate erroneously allowed"][36886]
|
|
|
|
|
- ["type parameter default erroneously allowed in invalid location"][36887]
|
|
|
|
|
- ["detects super or self keywords at the beginning of global path"][36888]
|
|
|
|
|
- ["two overlapping inherent impls define an item with the same name
|
|
|
|
|
were erroneously allowed"][36889]
|
|
|
|
|
- ["floating-point constants cannot be used in patterns"][36890]
|
|
|
|
|
- ["constants of struct or enum type can only be used in a pattern if
|
|
|
|
|
the struct or enum has `#[derive(PartialEq, Eq)]`"][36891]
|
|
|
|
|
- ["lifetimes or labels named `'_` were erroneously allowed"][36892]
|
|
|
|
|
* [Prohibit patterns in trait methods without bodies][37378]

|
|
|
|
|
they implement are rejected][37167]
|
|
|
|
|
* [Enums may not be unsized][37111]. Unsized enums are intended to
|
|
|
|
|
work but never have. For now they are forbidden.
|
|
|
|
|
* [Enforce the shadowing restrictions from RFC 1560 for today's macros][36767]

|
|
DICompositeType][36008]
|
|
|
|
|
* [Warn about multiple conflicting #[repr] hints][34623]
|

|
Diagnostics
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
* [Replace macro backtraces with labeled local uses][35702]
|
2017-11-21 15:33:45 +01:00
|
|
|
* [Improve error message for misplaced doc comments][33922]
|
2016-11-04 23:59:30 +01:00
|
|
|
* [Buffer unix and lock windows to prevent message interleaving][35975]
|
|
|
|
|
* [Update lifetime errors to specifically note temporaries][36171]
|
|
|
|
|
* [Special case a few colors for Windows][36178]
|
|
|
|
|
* [Suggest `use self` when such an import resolves][36289]
|
|
|
|
|
* [Be more specific when type parameter shadows primitive type][36338]
|
|
|
|
|
* Many minor improvements
|
|
|
|
|
|
|
|
|
|
Compile-time Optimizations
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
* [Compute and cache HIR hashes at beginning][35854]
|
|
|
|
|
* [Don't hash types in loan paths][36004]
|
|
|

|
|
|
|
|
* [Only instantiate #[inline] functions in codegen units referencing
|
|
|
|
|
them][36524]. This leads to big improvements in cases where crates export
|
|
|
|
|
define many inline functions without using them directly.
|
|
|
|
|
* [Lazily allocate TypedArena's first chunk][36592]
|
|
|
|
|
* [Don't allocate during default HashSet creation][36734]

Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* The `#[deprecated]` attribute when applied to an API will generate
|
|
|
|
|
warnings when used. The warnings may be suppressed with
|
|
|
|
|
`#[allow(deprecated)]`. [RFC 1270].
|
|
|
|
|
* [`fn` item types are zero sized, and each `fn` names a unique
|
|
|
|
|
type][1.9fn]. This will break code that transmutes `fn`s, so calling
|
|
|
|
|
`transmute` on a `fn` type will generate a warning for a few cycles,
|
|
|
|
|
then will be converted to an error.
|
|
|
|
|
* [Field and method resolution understand visibility, so private
|
|
|
|
|
fields and methods cannot prevent the proper use of public fields
|
|
|
|
|
and methods][1.9fv].
|
|
|
|
|
* [The parser considers unicode codepoints in the
|
|
|
|
|
`PATTERN_WHITE_SPACE` category to be whitespace][1.9ws].

Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* [`std::sync::Once` is poisoned if its initialization function
|
|
|
|
|
fails][1.9o].
|
|
|
|
|
* [`cell::Ref` and `cell::RefMut` can contain unsized types][1.9cu].
|
|
|
|
|
* [Most types implement `fmt::Debug`][1.9db].
|
|
|
|
|
* [The default buffer size used by `BufReader` and `BufWriter` was
|
|
|
|
|
reduced to 8K, from 64K][1.9bf]. This is in line with the buffer size
|
|
|
|
|
used by other languages.
|
|
|
|
|
* [`Instant`, `SystemTime` and `Duration` implement `+=` and `-=`.
|
|
|
|
|
`Duration` additionally implements `*=` and `/=`][1.9ta].
|
|
|
|
|
* [`Skip` is a `DoubleEndedIterator`][1.9sk].
|
|
|
|
|
* [`From<[u8; 4]>` is implemented for `Ipv4Addr`][1.9fi].
|
|

|
* [`Chain` implements `BufRead`][1.9ch].

Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* [Cargo can now run concurrently][1.9cc].
|
|
|
|
|
* [Top-level overrides allow specific revisions of crates to be
|
|
|
|
|
overridden through the entire crate graph][1.9ct]. This is intended
|
|
|
|
|
to make upgrades easier for large projects, by allowing crates to be
|
|
|
|
|
forked temporarily until they've been upgraded and republished.
|
|
|
|
|
* [Cargo exports a `CARGO_PKG_AUTHORS` environment variable][1.9cp].
|
|
|
|
|
* [Cargo will pass the contents of the `RUSTFLAGS` variable to `rustc`
|
|
|
|
|
on the commandline][1.9cf]. `rustc` arguments can also be specified
|
|
|
|
|
in the `build.rustflags` configuration key.

Performance
|
|
|
|
|
-----------
|
|
|
|
|
|
2016-09-30 00:26:02 +02:00
|
|
|
* [The time complexity of comparing variables for equivalence during type
|
2016-04-16 10:55:33 +02:00
|
|
|
unification is reduced from _O_(_n_!) to _O_(_n_)][1.9tu]. This leads
|
2016-04-15 22:33:50 +02:00
|
|
|
to major compilation time improvement in some scenarios.
|
2016-04-09 03:08:52 +02:00
|
|
|
* [`ToString` is specialized for `str`, giving it the same performance
|
|
|
|
|
as `to_owned`][1.9ts].
|
|
|
|
|
* [Spawning processes with `Command::output` no longer creates extra
|
|
|
|
|
threads][1.9sp].
|
|
|
|
|
* [`#[derive(PartialEq)]` and `#[derive(PartialOrd)]` emit less code
|
|
|
|
|
for C-like enums][1.9cl].
|

|
|
|

|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* [Passing the `--quiet` flag to a test runner will produce
|
|
|
|
|
much-abbreviated output][1.9q].
|
|
|
|
|
* The Rust Project now publishes std binaries for the
|
|
|
|
|
`mips-unknown-linux-musl`, `mipsel-unknown-linux-musl`, and
|
|
|
|
|
`i586-pc-windows-msvc` targets.

Version 1.8.0 (2016-04-14)
|
|
|
|
|
==========================
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* Rust supports overloading of compound assignment statements like
|
|
|
|
|
`+=` by implementing the [`AddAssign`], [`SubAssign`],
|
|
|
|
|
[`MulAssign`], [`DivAssign`], [`RemAssign`], [`BitAndAssign`],
|
|
|
|
|
[`BitOrAssign`], [`BitXorAssign`], [`ShlAssign`], or [`ShrAssign`]
|
|
|
|
|
traits. [RFC 953].
|
|
|
|
|
* Empty structs can be defined with braces, as in `struct Foo { }`, in
|
|
|
|
|
addition to the non-braced form, `struct Foo;`. [RFC 218].
|
|
|
|
|
|
|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* Stabilized APIs:
|
|
|
|
|
* [`str::encode_utf16`][] (renamed from `utf16_units`)
|
|
|
|
|
* [`str::EncodeUtf16`][] (renamed from `Utf16Units`)
|
|
|
|
|
* [`Ref::map`]
|
|
|
|
|
* [`RefMut::map`]
|
|
|
|
|
* [`ptr::drop_in_place`]
|
|
|
|
|
* [`time::Instant`]
|
|
|
|
|
* [`time::SystemTime`]
|
|
|
|
|
* [`Instant::now`]
|
|
|
|
|
* [`Instant::duration_since`][] (renamed from `duration_from_earlier`)
|
|
|
|
|
* [`Instant::elapsed`]
|
|
|
|
|
* [`SystemTime::now`]
|
|
|
|
|
* [`SystemTime::duration_since`][] (renamed from `duration_from_earlier`)
|
|
|
|
|
* [`SystemTime::elapsed`]
|
|
|
|
|
* Various `Add`/`Sub` impls for `Time` and `SystemTime`
|
|
|
|
|
* [`SystemTimeError`]
|
|
|
|
|
* [`SystemTimeError::duration`]
|
|
|
|
|
* Various impls for `SystemTimeError`
|
|
|
|
|
* [`UNIX_EPOCH`]
|
|
|
|
|
* [`AddAssign`], [`SubAssign`], [`MulAssign`], [`DivAssign`],
|
|
|
|
|
[`RemAssign`], [`BitAndAssign`], [`BitOrAssign`],
|
|
|
|
|
[`BitXorAssign`], [`ShlAssign`], [`ShrAssign`].
|
|
|
|
|
* [The `write!` and `writeln!` macros correctly emit errors if any of
|
|
|
|
|
their arguments can't be formatted][1.8w].
|
|
|
|
|
* [Various I/O functions support large files on 32-bit Linux][1.8l].
|
|
|
|
|
* [The Unix-specific `raw` modules, which contain a number of
|
|
|
|
|
redefined C types are deprecated][1.8r], including `os::raw::unix`,
|
|
|
|
|
`os::raw::macos`, and `os::raw::linux`. These modules defined types
|
|
|
|
|
such as `ino_t` and `dev_t`. The inconsistency of these definitions
|
|
|
|
|
across platforms was making it difficult to implement `std`
|
|
|
|
|
correctly. Those that need these definitions should use the `libc`
|
|
|
|
|
crate. [RFC 1415].
|
|
|
|
|
* The Unix-specific `MetadataExt` traits, including
|
|
|
|
|
`os::unix::fs::MetadataExt`, which expose values such as inode
|
|
|
|
|
numbers [no longer return platform-specific types][1.8r], but
|
|
|
|
|
instead return widened integers. [RFC 1415].
|
|
|
|
|
* [`btree_set::{IntoIter, Iter, Range}` are covariant][1.8cv].
|
|
|
|
|
* [Atomic loads and stores are not volatile][1.8a].
|
|
|
|
|
* [All types in `sync::mpsc` implement `fmt::Debug`][1.8mp].
|
|
|
|
|
|
|
|
|
|
Performance
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
* [Inlining hash functions lead to a 3% compile-time improvement in
|
|
|
|
|
some workloads][1.8h].
|
|
|
|
|
* When using jemalloc, its symbols are [unprefixed so that it
|
|
|
|
|
overrides the libc malloc implementation][1.8h]. This means that for
|
|
|
|
|
rustc, LLVM is now using jemalloc, which results in a 6%
|
|
|
|
|
compile-time improvement on a specific workload.
|
|
|
|
|
* [Avoid quadratic growth in function size due to cleanups][1.8cu].
|
|
|
|
|
|
|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* [32-bit MSVC builds finally implement unwinding][1.8ms].
|
|
|
|
|
i686-pc-windows-msvc is now considered a tier-1 platform.
|
|
|
|
|
* [The `--print targets` flag prints a list of supported targets][1.8t].
|
|
|
|
|
* [The `--print cfg` flag prints the `cfg`s defined for the current
|
|
|
|
|
target][1.8cf].
|
|
|
|
|
* [`rustc` can be built with an new Cargo-based build system, written
|
|
|
|
|
in Rust][1.8b]. It will eventually replace Rust's Makefile-based
|
|
|
|
|
build system. To enable it configure with `configure --rustbuild`.
|
|
|
|
|
* [Errors for non-exhaustive `match` patterns now list up to 3 missing
|
|
|
|
|
variants while also indicating the total number of missing variants
|
|
|
|
|
if more than 3][1.8m].
|
|
|
|
|
* [Executable stacks are disabled on Linux and BSD][1.8nx].
|
|
|
|
|
* The Rust Project now publishes binary releases of the standard
|
|
|
|
|
library for a number of tier-2 targets:
|
|
|
|
|
`armv7-unknown-linux-gnueabihf`, `powerpc-unknown-linux-gnu`,
|
|
|
|
|
`powerpc64-unknown-linux-gnu`, `powerpc64le-unknown-linux-gnu`
|
|
|
|
|
`x86_64-rumprun-netbsd`. These can be installed with
|
|
|
|
|
tools such as [multirust][1.8mr].
|
|
|
|
|
|
|
|
|
|
Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* [`cargo init` creates a new Cargo project in the current
|
|
|
|
|
directory][1.8ci]. It is otherwise like `cargo new`.
|
|
|
|
|
* [Cargo has configuration keys for `-v` and
|
|
|
|
|
`--color`][1.8cc]. `verbose` and `color`, respectively, go in the
|
|
|
|
|
`[term]` section of `.cargo/config`.
|
|
|
|
|
* [Configuration keys that evaluate to strings or integers can be set
|
|
|
|
|
via environment variables][1.8ce]. For example the `build.jobs` key
|
|
|
|
|
can be set via `CARGO_BUILD_JOBS`. Environment variables take
|
|
|
|
|
precedence over config files.
|
|
|
|
|
* [Target-specific dependencies support Rust `cfg` syntax for
|
|
|
|
|
describing targets][1.8cfg] so that dependencies for multiple
|
|
|
|
|
targets can be specified together. [RFC 1361].
|
|
|
|
|
* [The environment variables `CARGO_TARGET_ROOT`, `RUSTC`, and
|
|
|
|
|
`RUSTDOC` take precedence over the `build.target-dir`,
|
|
|
|
|
`build.rustc`, and `build.rustdoc` configuration values][1.8cv].
|
|
|
|
|
* [The child process tree is killed on Windows when Cargo is
|
|
|
|
|
killed][1.8ck].
|
|
|
|
|
* [The `build.target` configuration value sets the target platform,
|
|
|
|
|
like `--target`][1.8ct].
|
|
|
|
|
|
|
|
|
|
Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* [Unstable compiler flags have been further restricted][1.8u]. Since
|
|
|
|
|
1.0 `-Z` flags have been considered unstable, and other flags that
|
|
|
|
|
were considered unstable additionally required passing `-Z
|
|
|
|
|
unstable-options` to access. Unlike unstable language and library
|
|
|
|
|
features though, these options have been accessible on the stable
|
|
|
|
|
release channel. Going forward, *new unstable flags will not be
|
|
|
|
|
available on the stable release channel*, and old unstable flags
|
|
|
|
|
will warn about their usage. In the future, all unstable flags will
|
|
|
|
|
be unavailable on the stable release channel.
|
|
|
|
|
* [It is no longer possible to `match` on empty enum variants using
|
|
|
|
|
the `Variant(..)` syntax][1.8v]. This has been a warning since 1.6.
|
|
|
|
|
* The Unix-specific `MetadataExt` traits, including
|
|
|
|
|
`os::unix::fs::MetadataExt`, which expose values such as inode
|
|
|
|
|
numbers [no longer return platform-specific types][1.8r], but
|
|
|
|
|
instead return widened integers. [RFC 1415].
|
|
|
|
|
* [Modules sourced from the filesystem cannot appear within arbitrary
|
2016-04-11 20:31:00 +02:00
|
|
|
blocks, but only within other modules][1.8mf].
|
2016-04-08 01:16:35 +02:00
|
|
|
* [`--cfg` compiler flags are parsed strictly as identifiers][1.8c].
|
|
|
|
|
* On Unix, [stack overflow triggers a runtime abort instead of a
|
|
|
|
|
SIGSEGV][1.8so].
|
|
|
|
|
* [`Command::spawn` and its equivalents return an error if any of
|
|
|
|
|
its command-line arguments contain interior `NUL`s][1.8n].
|
|
|
|
|
* [Tuple and unit enum variants from other crates are in the type
|
|
|
|
|
namespace][1.8tn].
|
|
|
|
|
* [On Windows `rustc` emits `.lib` files for the `staticlib` library
|
|
|
|
|
type instead of `.a` files][1.8st]. Additionally, for the MSVC
|
|
|
|
|
toolchain, `rustc` emits import libraries named `foo.dll.lib`
|
|
|
|
|
instead of `foo.lib`.

|
|
|
* [Validating UTF-8 is faster by a factor of between 7 and 14x for
|
|
|
|
|
ASCII input][1.7utf8]. This means that creating `String`s and `str`s
|
|
|
|
|
from bytes is faster.
|
|
|
|
|
* [The performance of `LineWriter` (and thus `io::stdout`) was
|
|
|
|
|
improved by using `memchr` to search for newlines][1.7m].
|
|
|
|
|
* [`f32::to_degrees` and `f32::to_radians` are stable][1.7f]. The
|
|
|
|
|
`f64` variants were stabilized previously.
|
2016-02-26 22:21:02 +01:00
|
|
|
* [`BTreeMap` was rewritten to use less memory and improve the performance
|
2016-02-27 12:19:08 +01:00
|
|
|
of insertion and iteration, the latter by as much as 5x][1.7bm].
|
2016-01-22 01:02:28 +01:00
|
|
|
* [`BTreeSet` and its iterators, `Iter`, `IntoIter`, and `Range` are
|
|
|
|
|
covariant over their contained type][1.7bt].
|
|
|
|
|
* [`LinkedList` and its iterators, `Iter` and `IntoIter` are covariant
|
|
|
|
|
over their contained type][1.7ll].
|
|
|
|
|
* [`str::replace` now accepts a `Pattern`][1.7rp], like other string
|
|
|
|
|
searching methods.
|
|
|
|
|
* [`Any` is implemented for unsized types][1.7a].
|
|
|
|
|
* [`Hash` is implemented for `Duration`][1.7h].

Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* [When running tests with `--test`, rustdoc will pass `--cfg`
|
|
|
|
|
arguments to the compiler][1.7dt].
|
2016-02-16 12:40:06 +01:00
|
|
|
* [The compiler is built with RPATH information by default][1.7rpa].
|
2016-01-22 01:02:28 +01:00
|
|
|
This means that it will be possible to run `rustc` when installed in
|
|
|
|
|
unusual configurations without configuring the dynamic linker search
|
|
|
|
|
path explicitly.
|
2016-02-16 12:40:06 +01:00
|
|
|
* [`rustc` passes `--enable-new-dtags` to GNU ld][1.7dta]. This makes
|
2016-01-22 01:02:28 +01:00
|
|
|
any RPATH entries (emitted with `-C rpath`) *not* take precedence
|
|
|
|
|
over `LD_LIBRARY_PATH`.
|
|
|
|
|
|
|
|
|
|
Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* [`cargo rustc` accepts a `--profile` flag that runs `rustc` under
|
|
|
|
|
any of the compilation profiles, 'dev', 'bench', or 'test'][1.7cp].
|
|
|
|
|
* [The `rerun-if-changed` build script directive no longer causes the
|
|
|
|
|
build script to incorrectly run twice in certain scenarios][1.7rr].

Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
2016-02-29 19:35:43 +01:00
|
|
|
* Soundness fixes to the interactions between associated types and
|
|
|
|
|
lifetimes, specified in [RFC 1214], [now generate errors][1.7sf] for
|
|
|
|
|
code that violates the new rules. This is a significant change that
|
|
|
|
|
is known to break existing code, so it has emitted warnings for the
|
|
|
|
|
new error cases since 1.4 to give crate authors time to adapt. The
|
|
|
|
|
details of what is changing are subtle; read the RFC for more.
|
2016-01-22 01:02:28 +01:00
|
|
|
* [Several bugs in the compiler's visibility calculations were
|
|
|
|
|
fixed][1.7v]. Since this was found to break significant amounts of
|
|
|
|
|
code, the new errors will be emitted as warnings for several release
|
|
|
|
|
cycles, under the `private_in_public` lint.
|
|
|
|
|
* Defaulted type parameters were accidentally accepted in positions
|
|
|
|
|
that were not intended. In this release, [defaulted type parameters
|
|
|
|
|
appearing outside of type definitions will generate a
|
|
|
|
|
warning][1.7d], which will become an error in future releases.
|
2016-03-17 20:15:22 +01:00
|
|
|
* [Parsing "." as a float results in an error instead of 0][1.7p].
|
|
|
|
|
That is, `".".parse::<f32>()` returns `Err`, not `Ok(0.0)`.
|
2016-01-22 01:02:28 +01:00
|
|
|
* [Borrows of closure parameters may not outlive the closure][1.7bc].

Version 1.6.0 (2016-01-21)

==========================

|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* The `#![no_std]` attribute causes a crate to not be linked to the
|
|
|
|
|
standard library, but only the [core library][1.6co], as described
|
|
|
|
|
in [RFC 1184]. The core library defines common types and traits but
|
|
|
|
|
has no platform dependencies whatsoever, and is the basis for Rust
|
|
|
|
|
software in environments that cannot support a full port of the
|
|
|
|
|
standard library, such as operating systems. Most of the core
|
|
|
|
|
library is now stable.

|

|
2016-01-19 01:18:11 +01:00
|
|
|
* The [core library][1.6co] is stable, as are most of its APIs.
|
|
|
|
|
* [The `assert_eq!` macro supports arguments that don't implement
|
|
|
|
|
`Sized`][1.6ae], such as arrays. In this way it behaves more like
|
|
|
|
|
`assert!`.
|
|
|
|
|
* Several timer functions that take duration in milliseconds [are
|
|
|
|
|
deprecated in favor of those that take `Duration`][1.6ms]. These
|
|
|
|
|
include `Condvar::wait_timeout_ms`, `thread::sleep_ms`, and
|
|
|
|
|
`thread::park_timeout_ms`.
|
|
|
|
|
* The algorithm by which `Vec` reserves additional elements was
|
|
|
|
|
[tweaked to not allocate excessive space][1.6a] while still growing
|
|
|
|
|
exponentially.
|
|
|
|
|
* `From` conversions are [implemented from integers to floats][1.6f]
|
|
|
|
|
in cases where the conversion is lossless. Thus they are not
|
|
|
|
|
implemented for 32-bit ints to `f32`, nor for 64-bit ints to `f32`
|
|
|
|
|
or `f64`. They are also not implemented for `isize` and `usize`
|
|
|
|
|
because the implementations would be platform-specific. `From` is
|
|
|
|
|
also implemented from `f32` to `f64`.
|
|
|
|
|
* `From<&Path>` and `From<PathBuf>` are implemented for `Cow<Path>`.
|
|
|
|
|
* `From<T>` is implemented for `Box<T>`, `Rc<T>` and `Arc<T>`.
|
|
|
|
|
* `IntoIterator` is implemented for `&PathBuf` and `&Path`.
|
|
|
|
|
* [`BinaryHeap` was refactored][1.6bh] for modest performance
|
|
|
|
|
improvements.
|
|
|
|
|
* Sorting slices that are already sorted [is 50% faster in some
|
|
|
|
|
cases][1.6s].
|
|
|
|
|
|
|
|
|
|
Cargo
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
* Cargo will look in `$CARGO_HOME/bin` for subcommands [by default][1.6c].
|
|
|
|
|
* Cargo build scripts can specify their dependencies by emitting the
|
|
|
|
|
[`rerun-if-changed`][1.6rr] key.
|
|
|
|
|
* crates.io will reject publication of crates with dependencies that
|
|
|
|
|
have a wildcard version constraint. Crates with wildcard
|
|
|
|
|
dependencies were seen to cause a variety of problems, as described
|
|
|
|
|
in [RFC 1241]. Since 1.5 publication of such crates has emitted a
|
|
|
|
|
warning.
|
|
|
|
|
* `cargo clean` [accepts a `--release` flag][1.6cc] to clean the
|
|
|
|
|
release folder. A variety of artifacts that Cargo failed to clean
|
|
|
|
|
are now correctly deleted.
|
|
|
|
|
|
|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* The `unreachable_code` lint [warns when a function call's argument
|
|
|
|
|
diverges][1.6dv].
|
|
|
|
|
* The parser indicates [failures that may be caused by
|
|
|
|
|
confusingly-similar Unicode characters][1.6uc]
|
|
|
|
|
* Certain macro errors [are reported at definition time][1.6m], not
|
|
|
|
|
expansion.
|
|
|
|
|
|
|
|
|
|
Compatibility Notes
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
* The compiler no longer makes use of the [`RUST_PATH`][1.6rp]
|
|
|
|
|
environment variable when locating crates. This was a pre-cargo
|
|
|
|
|
feature for integrating with the package manager that was
|
|
|
|
|
accidentally never removed.
|
|
|
|
|
* [A number of bugs were fixed in the privacy checker][1.6p] that
|
|
|
|
|
could cause previously-accepted code to break.
|
|
|
|
|
* [Modules and unit/tuple structs may not share the same name][1.6ts].
|
|
|
|
|
* [Bugs in pattern matching unit structs were fixed][1.6us]. The tuple
|
|
|
|
|
struct pattern syntax (`Foo(..)`) can no longer be used to match
|
|
|
|
|
unit structs. This is a warning now, but will become an error in
|
|
|
|
|
future releases. Patterns that share the same name as a const are
|
|
|
|
|
now an error.
|
|
|
|
|
* A bug was fixed that causes [rustc not to apply default type
|
|
|
|
|
parameters][1.6xc] when resolving certain method implementations of
|
|
|
|
|
traits defined in other crates.

|
|
|
|
|
|
|
|
|
|

Highlights
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
* Stabilized APIs:

|
|
|
|
|
[`Formatter::precision`], [`Formatter::sign_aware_zero_pad`],

|
|
|
|
|

|
|
|
|
|
[`Iterator::ge`], [`Iterator::gt`], [`Iterator::le`],
|
|
|
|
|
[`Iterator::lt`], [`Iterator::ne`], [`Iterator::partial_cmp`],
|
|
|
|
|
[`Path::canonicalize`], [`Path::exists`], [`Path::is_dir`],
|
|
|
|
|
[`Path::is_file`], [`Path::metadata`], [`Path::read_dir`],
|
|
|
|
|
[`Path::read_link`], [`Path::symlink_metadata`],
|
|
|
|
|
[`Utf8Error::valid_up_to`], [`Vec::resize`],
|
|
|
|
|
[`VecDeque::as_mut_slices`], [`VecDeque::as_slices`],
|
|
|
|
|
[`VecDeque::insert`], [`VecDeque::shrink_to_fit`],
|
|
|
|
|
[`VecDeque::swap_remove_back`], [`VecDeque::swap_remove_front`],
|
|

|
|
|

|
[`str::slice_mut_unchecked`], [`string::ParseError`].
|
|
|
|
|
* Rust applications hosted on crates.io can be installed locally to
|
|
|
|
|
`~/.cargo/bin` with the [`cargo install`] command. Among other
|
|
|
|
|
things this makes it easier to augment Cargo with new subcommands:
|
|
|
|
|
when a binary named e.g. `cargo-foo` is found in `$PATH` it can be
|
|
|
|
|
invoked as `cargo foo`.
|
|
|
|
|
* Crates with wildcard (`*`) dependencies will [emit warnings when
|
|
|
|
|
published][1.5w]. In 1.6 it will no longer be possible to publish
|
|
|
|
|
crates with wildcard dependencies.

|
Breaking Changes
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
* The rules determining when a particular lifetime must outlive
|
|
|
|
|
a particular value (known as '[dropck]') have been [modified
|
|
|
|
|
to not rely on parametricity][1.5p].
|
|
|
|
|
* [Implementations of `AsRef` and `AsMut` were added to `Box`, `Rc`,
|
|
|
|
|
and `Arc`][1.5a]. Because these smart pointer types implement
|
|
|
|
|
`Deref`, this causes breakage in cases where the interior type
|
|
|
|
|
contains methods of the same name.
|
|
|
|
|
* [Correct a bug in Rc/Arc][1.5c] that caused [dropck] to be unaware
|
|
|
|
|
that they could drop their content. Soundness fix.
|
|
|
|
|
* All method invocations are [properly checked][1.5wf1] for
|
|
|
|
|
[well-formedness][1.5wf2]. Soundness fix.
|
|
|
|
|
* Traits whose supertraits contain `Self` are [not object
|
|
|
|
|
safe][1.5o]. Soundness fix.
|
|
|
|
|
* Target specifications support a [`no_default_libraries`][1.5nd]
|
|
|
|
|
setting that controls whether `-nodefaultlibs` is passed to the
|
|
|
|
|
linker, and in turn the `is_like_windows` setting no longer affects
|
|
|
|
|
the `-nodefaultlibs` flag.
|
|
|
|
|
* `#[derive(Show)]`, long-deprecated, [has been removed][1.5ds].
|
|
|
|
|
* The `#[inline]` and `#[repr]` attributes [can only appear
|
|
|
|
|
in valid locations][1.5at].
|
|
|
|
|
* Native libraries linked from the local crate are [passed to
|
|
|
|
|
the linker before native libraries from upstream crates][1.5nl].
|
|
|
|
|
* Two rarely-used attributes, `#[no_debug]` and
|
|
|
|
|
`#[omit_gdb_pretty_printer_section]` [are feature gated][1.5fg].
|
|
|
|
|
* Negation of unsigned integers, which has been a warning for
|
|
|
|
|
several releases, [is now behind a feature gate and will
|
|
|
|
|
generate errors][1.5nu].
|
|
|
|
|
* The parser accidentally accepted visibility modifiers on
|
|
|
|
|
enum variants, a bug [which has been fixed][1.5ev].
|
|
|
|
|
* [A bug was fixed that allowed `use` statements to import unstable
|
|
|
|
|
features][1.5use].
|
|
|
|
|
|
|
|
|
|
Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* When evaluating expressions at compile-time that are not
|
|
|
|
|
compile-time constants (const-evaluating expressions in non-const
|
|
|
|
|
contexts), incorrect code such as overlong bitshifts and arithmetic
|
|
|
|
|
overflow will [generate a warning instead of an error][1.5ce],
|
|
|
|
|
delaying the error until runtime. This will allow the
|
|
|
|
|
const-evaluator to be expanded in the future backwards-compatibly.
|
|
|
|
|
* The `improper_ctypes` lint [no longer warns about using `isize` and
|
|
|
|
|
`usize` in FFI][1.5ict].
|
|
|
|
|
|
|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* `Arc<T>` and `Rc<T>` are [covariant with respect to `T` instead of
|
|
|
|
|
invariant][1.5c].
|
|
|
|
|
* `Default` is [implemented for mutable slices][1.5d].
|
|
|
|
|
* `FromStr` is [implemented for `SockAddrV4` and `SockAddrV6`][1.5s].
|
|
|
|
|
* There are now `From` conversions [between floating point
|
|
|
|
|
types][1.5f] where the conversions are lossless.
|
2017-11-21 15:33:45 +01:00
|
|
|
* There are now `From` conversions [between integer types][1.5i] where
|
2015-12-04 04:37:30 +01:00
|
|
|
the conversions are lossless.
|
|
|
|
|
* [`fs::Metadata` implements `Clone`][1.5fs].
|
|
|
|
|
* The `parse` method [accepts a leading "+" when parsing
|
|
|
|
|
integers][1.5pi].
|
|
|
|
|
* [`AsMut` is implemented for `Vec`][1.5am].
|
|
|
|
|
* The `clone_from` implementations for `String` and `BinaryHeap` [have
|
|
|
|
|
been optimized][1.5cf] and no longer rely on the default impl.
|
|
|
|
|
* The `extern "Rust"`, `extern "C"`, `unsafe extern "Rust"` and
|
|
|
|
|
`unsafe extern "C"` function types now [implement `Clone`,
|
|
|
|
|
`PartialEq`, `Eq`, `PartialOrd`, `Ord`, `Hash`, `fmt::Pointer`, and
|
|
|
|
|
`fmt::Debug` for up to 12 arguments][1.5fp].
|
|
|
|
|
* [Dropping `Vec`s is much faster in unoptimized builds when the
|
|
|
|
|
element types don't implement `Drop`][1.5dv].
|
|
|
|
|
* A bug that caused in incorrect behavior when [combining `VecDeque`
|
|
|
|
|
with zero-sized types][1.5vdz] was resolved.
|
|
|
|
|
* [`PartialOrd` for slices is faster][1.5po].
|
|
|
|
|
|
|
|
|
|
Miscellaneous
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
* [Crate metadata size was reduced by 20%][1.5md].
|
|
|
|
|
* [Improvements to code generation reduced the size of libcore by 3.3
|
|
|
|
|
MB and rustc's memory usage by 18MB][1.5m].
|
|
|
|
|
* [Improvements to deref translation increased performance in
|
|
|
|
|
unoptimized builds][1.5dr].
|
|
|
|
|
* Various errors in trait resolution [are deduplicated to only be
|
|
|
|
|
reported once][1.5te].
|
|
|
|
|
* Rust has preliminary [support for rumprun kernels][1.5rr].
|
|
|
|
|
* Rust has preliminary [support for NetBSD on amd64][1.5na].

Highlights
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
* Windows builds targeting the 64-bit MSVC ABI and linker (instead of
|
|
|
|
|
GNU) are now supported and recommended for use.

Breaking Changes
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
* [Several changes have been made to fix type soundness and improve
|
|
|
|
|
the behavior of associated types][sound]. See [RFC 1214]. Although
|
|
|
|
|
we have mostly introduced these changes as warnings this release, to
|
|
|
|
|
become errors next release, there are still some scenarios that will
|
|
|
|
|
see immediate breakage.
|
|
|
|
|
* [The `str::lines` and `BufRead::lines` iterators treat `\r\n` as
|
|
|
|
|
line breaks in addition to `\n`][crlf].
|
|
|
|
|
* [Loans of `'static` lifetime extend to the end of a function][stat].
|
2015-10-29 19:36:56 +01:00
|
|
|
* [`str::parse` no longer introduces avoidable rounding error when
|
|
|
|
|
parsing floating point numbers. Together with earlier changes to
|
|
|
|
|
float formatting/output, "round trips" like f.to_string().parse()
|
|
|
|
|
now preserve the value of f exactly. Additionally, leading plus
|
|
|
|
|
signs are now accepted][fp3].

Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* `use` statements that import multiple items [can now rename
|
|
|
|
|
them][i], as in `use foo::{bar as kitten, baz as puppy}`.
|
|
|
|
|
* [Binops work correctly on fat pointers][binfat].
|
|
|
|
|
* `pub extern crate`, which does not behave as expected, [issues a
|
|
|
|
|
warning][pec] until a better solution is found.

`Result`][into2].
|
2015-10-28 00:25:33 +01:00
|
|

|
2017-11-21 15:33:45 +01:00
|
|
|
Copy`][ext] as part of [RFC 839]. This will cause type inference
|
2015-10-29 19:36:56 +01:00
|
|
|
breakage in rare situations.
|
2015-10-28 00:25:33 +01:00

|
|

|
|
|
|
Miscellaneous
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
* The compiler [no longer uses the 'morestack' feature to prevent
|
|
|
|
|
stack overflow][mm]. Instead it uses guard pages and stack
|
|
|
|
|
probes (though stack probes are not yet implemented on any platform
|
|
|
|
|
but Windows).
|
|
|
|
|
* [The compiler matches traits faster when projections are involved][p].
|
|
|
|
|
* The 'improper_ctypes' lint [no longer warns about use of `isize` and
|
|
|
|
|
`usize`][ffi].
|
|
|
|
|
* [Cargo now displays useful information about what its doing during
|
|
|
|
|
`cargo update`][cu].

==============================
|
|
|

Highlights
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
* The [new object lifetime defaults][nold] have been [turned
|
|
|
|
|
on][nold2] after a cycle of warnings about the change. Now types
|
|
|
|
|
like `&'a Box<Trait>` (or `&'a Rc<Trait>`, etc) will change from
|
|
|
|
|
being interpreted as `&'a Box<Trait+'a>` to `&'a
|
|
|
|
|
Box<Trait+'static>`.
|
|
|
|
|
* [The Rustonomicon][nom] is a new book in the official documentation
|
|
|
|
|
that dives into writing unsafe Rust.
|
|
|
|
|
* The [`Duration`] API, [has been stabilized][ds]. This basic unit of
|
|
|
|
|
timekeeping is employed by other std APIs, as well as out-of-tree
|
|
|
|
|
time crates.

|
----------------
|
|
|
|
|
|
|
|
|
|
* The [new object lifetime defaults][nold] have been [turned
|
|
|
|
|
on][nold2] after a cycle of warnings about the change.
|
|
|
|
|
* There is a known [regression][lr] in how object lifetime elision is
|
|
|
|
|
interpreted, the proper solution for which is undetermined.
|
|
|
|
|
* The `#[prelude_import]` attribute, an internal implementation
|
|
|
|
|
detail, was accidentally stabilized previously. [It has been put
|
|
|
|
|
behind the `prelude_import` feature gate][pi]. This change is
|
|
|
|
|
believed to break no existing code.
|
|
|
|
|
* The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is
|
|
|
|
|
[more sane for dynamically sized types][dst3]. Code that relied on
|
|
|
|
|
the previous behavior is thought to be broken.
|
|
|
|
|
* The `dropck` rules, which checks that destructors can't access
|
|
|
|
|
destroyed values, [have been updated][dropck] to match the
|
|
|
|
|
[RFC][dropckrfc]. This fixes some soundness holes, and as such will
|
|
|
|
|
cause some previously-compiling code to no longer build.

Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* The [new object lifetime defaults][nold] have been [turned
|
|
|
|
|
on][nold2] after a cycle of warnings about the change.
|
|
|
|
|
* Semicolons may [now follow types and paths in
|
|
|
|
|
macros](https://github.com/rust-lang/rust/pull/27000).
|
|
|
|
|
* The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is
|
|
|
|
|
[more sane for dynamically sized types][dst3]. Code that relied on
|
|
|
|
|
the previous behavior is not known to exist, and suspected to be
|
|
|
|
|
broken.
|
|
|
|
|
* `'static` variables [may now be recursive][st].
|
|
|
|
|
* `ref` bindings choose between [`Deref`] and [`DerefMut`]
|
|
|
|
|
implementations correctly.
|
|
|
|
|
* The `dropck` rules, which checks that destructors can't access
|
|
|
|
|
destroyed values, [have been updated][dropck] to match the
|
|
|
|
|
[RFC][dropckrfc].
|

|
|
|
|
Libraries
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
* The [`Duration`] API, [has been stabilized][ds], as well as the
|
|
|
|
|
`std::time` module, which presently contains only `Duration`.
|
|
|
|
|
* `Box<str>` and `Box<[T]>` both implement `Clone`.
|
|
|
|
|
* The owned C string, [`CString`], implements [`Borrow`] and the
|
|
|
|
|
borrowed C string, [`CStr`], implements [`ToOwned`]. The two of
|
|
|
|
|
these allow C strings to be borrowed and cloned in generic code.
|
|
|
|
|
* [`CStr`] implements [`Debug`].
|
|
|
|
|
* [`AtomicPtr`] implements [`Debug`].
|
|
|
|
|
* [`Error`] trait objects [can be downcast to their concrete types][e]
|
|
|
|
|
in many common configurations, using the [`is`], [`downcast`],
|
|
|
|
|
[`downcast_ref`] and [`downcast_mut`] methods, similarly to the
|
|
|
|
|
[`Any`] trait.
|
|
|
|
|
* Searching for substrings now [employs the two-way algorithm][search]
|
|
|
|
|
instead of doing a naive search. This gives major speedups to a
|
|
|
|
|
number of methods, including [`contains`][sc], [`find`][sf],
|
|
|
|
|
[`rfind`][srf], [`split`][ss]. [`starts_with`][ssw] and
|
|
|
|
|
[`ends_with`][sew] are also faster.
|
|
|
|
|
* The performance of `PartialEq` for slices is [much faster][ps].
|
|
|
|
|
* The [`Hash`] trait offers the default method, [`hash_slice`], which
|
|
|
|
|
is overridden and optimized by the implementations for scalars.
|
|
|
|
|
* The [`Hasher`] trait now has a number of specialized `write_*`
|
|
|
|
|
methods for primitive types, for efficiency.
|
|
|
|
|
* The I/O-specific error type, [`std::io::Error`][ie], gained a set of
|
|
|
|
|
methods for accessing the 'inner error', if any: [`get_ref`][iegr],
|
|
|
|
|
[`get_mut`][iegm], [`into_inner`][ieii]. As well, the implementation
|
|
|
|
|
of [`std::error::Error::cause`][iec] also delegates to the inner
|
|
|
|
|
error.
|
|
|
|
|
* [`process::Child`][pc] gained the [`id`] method, which returns a
|
|
|
|
|
`u32` representing the platform-specific process identifier.
|
|
|
|
|
* The [`connect`] method on slices is deprecated, replaced by the new
|
|
|
|
|
[`join`] method (note that both of these are on the *unstable*
|
|
|
|
|
[`SliceConcatExt`] trait, but through the magic of the prelude are
|
|
|
|
|
available to stable code anyway).
|
|
|
|
|
* The [`Div`] operator is implemented for [`Wrapping`] types.
|
|
|
|
|
* [`DerefMut` is implemented for `String`][dms].
|
|
|
|
|
* Performance of SipHash (the default hasher for `HashMap`) is
|
|
|
|
|
[better for long data][sh].
|
|
|
|
|
* [`AtomicPtr`] implements [`Send`].
|
|
|
|
|
* The [`read_to_end`] implementations for [`Stdin`] and [`File`]
|
2017-11-21 15:33:45 +01:00
|
|
|
are now [specialized to use uninitialized buffers for increased
|
2015-08-19 23:16:26 +02:00
|
|
|
performance][rte].
|
|
|
|
|
* Lifetime parameters of foreign functions [are now resolved
|
|
|
|
|
properly][f].
|
|
|
|
|

|
|
|
|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* Rust can now, with some coercion, [produce programs that run on
|
|
|
|
|
Windows XP][xp], though XP is not considered a supported platform.
|
|
|
|
|
* Porting Rust on Windows from the GNU toolchain to MSVC continues
|
|
|
|
|
([1][win1], [2][win2], [3][win3], [4][win4]). It is still not
|
|
|
|
|
recommended for use in 1.3, though should be fully-functional
|
|
|
|
|
in the [64-bit 1.4 beta][b14].
|
|
|
|
|
* On Fedora-based systems installation will [properly configure the
|
|
|
|
|
dynamic linker][fl].
|
|
|
|
|
* The compiler gained many new extended error descriptions, which can
|
|
|
|
|
be accessed with the `--explain` flag.
|
|
|
|
|
* The `dropck` pass, which checks that destructors can't access
|
|
|
|
|
destroyed values, [has been rewritten][dropck]. This fixes some
|
|
|
|
|
soundness holes, and as such will cause some previously-compiling
|
|
|
|
|
code to no longer build.
|
|
|
|
|
* `rustc` now uses [LLVM to write archive files where possible][ar].
|
|
|
|
|
Eventually this will eliminate the compiler's dependency on the ar
|
|
|
|
|
utility.
|
|
|
|
|
* Rust has [preliminary support for i686 FreeBSD][fb] (it has long
|
|
|
|
|
supported FreeBSD on x86_64).
|
|
|
|
|
* The [`unused_mut`][lum], [`unconditional_recursion`][lur],
|
|
|
|
|
[`improper_ctypes`][lic], and [`negate_unsigned`][lnu] lints are
|
|
|
|
|
more strict.
|
|
|
|
|
* If landing pads are disabled (with `-Z no-landing-pads`), [`panic!`
|
|
|
|
|
will kill the process instead of leaking][nlp].

Highlights
|
|
|
|
|
----------
|
|
|
|
|
|
2015-07-09 23:34:30 +02:00
|
|
|
* [Dynamically-sized-type coercions][dst] allow smart pointer types
|
|
|
|
|
like `Rc` to contain types without a fixed size, arrays and trait
|
|
|
|
|
objects, finally enabling use of `Rc<[T]>` and completing the
|
|
|
|
|
implementation of DST.
|
|
|
|
|
* [Parallel codegen][parcodegen] is now working again, which can
|
|
|
|
|
substantially speed up large builds in debug mode; It also gets
|
|
|
|
|
another ~33% speedup when bootstrapping on a 4 core machine (using 8
|
|
|
|
|
jobs). It's not enabled by default, but will be "in the near
|
|
|
|
|
future". It can be activated with the `-C codegen-units=N` flag to
|
|
|
|
|
`rustc`.
|
2015-07-30 23:27:54 +02:00
|
|
|
* This is the first release with [experimental support for linking
|
|
|
|
|
with the MSVC linker and lib C on Windows (instead of using the GNU
|
|
|
|
|
variants via MinGW)][win]. It is yet recommended only for the most
|
2017-11-21 15:33:45 +01:00
|
|
|
intrepid Rustaceans.
|
2015-07-30 23:27:54 +02:00
|
|
|
* Benchmark compilations are showing a 30% improvement in
|
|
|
|
|
bootstrapping over 1.1.

Breaking Changes
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
* The [`to_uppercase`] and [`to_lowercase`] methods on `char` now do
|
|
|
|
|
unicode case mapping, which is a previously-planned change in
|
|
|
|
|
behavior and considered a bugfix.
|
|
|
|
|
* [`mem::align_of`] now specifies [the *minimum alignment* for
|
|
|
|
|
T][align], which is usually the alignment programs are interested
|
|
|
|
|
in, and the same value reported by clang's
|
|
|
|
|
`alignof`. [`mem::min_align_of`] is deprecated. This is not known to
|
|
|
|
|
break real code.
|
2015-07-14 19:32:23 +02:00
|
|
|
* [The `#[packed]` attribute is no longer silently accepted by the
|
|
|
|
|
compiler][packed]. This attribute did nothing and code that
|
|
|
|
|
mentioned it likely did not work as intended.
|
2015-07-30 23:27:54 +02:00
|
|
|
* Associated type defaults are [now behind the
|
|
|
|
|
`associated_type_defaults` feature gate][ad]. In 1.1 associated type
|
|
|
|
|
defaults *did not work*, but could be mentioned syntactically. As
|
|
|
|
|
such this breakage has minimal impact.

Language
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
* Patterns with `ref mut` now correctly invoke [`DerefMut`] when
|
2018-07-30 17:41:19 +02:00
|
|
|
matching against dereferenceable values.

* The [`Extend`] trait, which grows a collection from an iterator, is
|
|
|
|
|
implemented over iterators of references, for `String`, `Vec`,
|
|
|
|
|
`LinkedList`, `VecDeque`, `EnumSet`, `BinaryHeap`, `VecMap`,
|
|
|
|
|
`BTreeSet` and `BTreeMap`. [RFC][extend-rfc].
|
|
|
|
|
* The [`iter::once`] function returns an iterator that yields a single
|
2015-07-30 23:27:54 +02:00
|
|
|
element, and [`iter::empty`] returns an iterator that yields no
|
2015-07-09 23:34:30 +02:00
|
|
|
elements.
|
|
|
|
|
* The [`matches`] and [`rmatches`] methods on `str` return iterators
|
|
|
|
|
over substring matches.
|
2015-07-30 23:27:54 +02:00
|
|
|
* [`Cell`] and [`RefCell`] both implement `Eq`.
|
2015-07-09 23:34:30 +02:00
|
|
|
* A number of methods for wrapping arithmetic are added to the
|
|
|
|
|
integral types, [`wrapping_div`], [`wrapping_rem`],
|
|
|
|
|
[`wrapping_neg`], [`wrapping_shl`], [`wrapping_shr`]. These are in
|
|
|
|
|
addition to the existing [`wrapping_add`], [`wrapping_sub`], and
|
|
|
|
|
[`wrapping_mul`] methods, and alternatives to the [`Wrapping`]
|
|
|
|
|
type.. It is illegal for the default arithmetic operations in Rust
|
|
|
|
|
to overflow; the desire to wrap must be explicit.
|
|
|
|
|
* The `{:#?}` formatting specifier [displays the alternate,
|
|
|
|
|
pretty-printed][debugfmt] form of the `Debug` formatter. This
|
|
|
|
|
feature was actually introduced prior to 1.0 with little
|
|
|
|
|
fanfare.
|
|
|
|
|
* [`fmt::Formatter`] implements [`fmt::Write`], a `fmt`-specific trait
|
|
|
|
|
for writing data to formatted strings, similar to [`io::Write`].
|
|
|
|
|
* [`fmt::Formatter`] adds 'debug builder' methods, [`debug_struct`],
|
|
|
|
|
[`debug_tuple`], [`debug_list`], [`debug_set`], [`debug_map`]. These
|
|
|
|
|
are used by code generators to emit implementations of [`Debug`].
|
|
|
|
|
* `str` has new [`to_uppercase`][strup] and [`to_lowercase`][strlow]
|
|
|
|
|
methods that convert case, following Unicode case mapping.
|
2015-08-03 22:19:21 +02:00
|
|
|
* It is now easier to handle poisoned locks. The [`PoisonError`]
|
2015-07-09 23:34:30 +02:00
|
|
|
type, returned by failing lock operations, exposes `into_inner`,
|
|
|
|
|
`get_ref`, and `get_mut`, which all give access to the inner lock
|
|
|
|
|
guard, and allow the poisoned lock to continue to operate. The
|
|
|
|
|
`is_poisoned` method of [`RwLock`] and [`Mutex`] can poll for a
|
|
|
|
|
poisoned lock without attempting to take the lock.
|
|
|
|
|
* On Unix the [`FromRawFd`] trait is implemented for [`Stdio`], and
|
|
|
|
|
[`AsRawFd`] for [`ChildStdin`], [`ChildStdout`], [`ChildStderr`].
|
|
|
|
|
On Windows the `FromRawHandle` trait is implemented for `Stdio`,
|
|
|
|
|
and `AsRawHandle` for `ChildStdin`, `ChildStdout`,
|
|
|
|
|
`ChildStderr`.
|
|
|
|
|
* [`io::ErrorKind`] has a new variant, `InvalidData`, which indicates
|
|
|
|
|
malformed input.

std: Stabilize a number of new fs features
This commit stabilizes the following APIs, slating them all to be cherry-picked
into the 1.1 release.
* fs::FileType (and transitively the derived trait implementations)
* fs::Metadata::file_type
* fs::FileType::is_dir
* fs::FileType::is_file
* fs::FileType::is_symlink
* fs::DirEntry::metadata
* fs::DirEntry::file_type
* fs::DirEntry::file_name
* fs::set_permissions
* fs::symlink_metadata
* os::raw::{self, *}
* os::{android, bitrig, linux, ...}::raw::{self, *}
* os::{android, bitrig, linux, ...}::fs::MetadataExt
* os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat
* os::unix::fs::PermissionsExt
* os::unix::fs::PermissionsExt::mode
* os::unix::fs::PermissionsExt::set_mode
* os::unix::fs::PermissionsExt::from_mode
* os::unix::fs::OpenOptionsExt
* os::unix::fs::OpenOptionsExt::mode
* os::unix::fs::DirEntryExt
* os::unix::fs::DirEntryExt::ino
* os::windows::fs::MetadataExt
* os::windows::fs::MetadataExt::file_attributes
* os::windows::fs::MetadataExt::creation_time
* os::windows::fs::MetadataExt::last_access_time
* os::windows::fs::MetadataExt::last_write_time
* os::windows::fs::MetadataExt::file_size
The `os::unix::fs::Metadata` structure was also removed entirely, moving all of
its associated methods into the `os::unix::fs::MetadataExt` trait instead. The
methods are all marked as `#[stable]` still.
As some minor cleanup, some deprecated and unstable fs apis were also removed:
* File::path
* Metadata::accessed
* Metadata::modified
Features that were explicitly left unstable include:
* fs::WalkDir - the semantics of this were not considered in the recent fs
expansion RFC.
* fs::DirBuilder - it's still not 100% clear if the naming is right here and if
the set of functionality exposed is appropriate.
* fs::canonicalize - the implementation on Windows here is specifically in
question as it always returns a verbatim path. Additionally the Unix
implementation is susceptible to buffer overflows on long paths unfortunately.
* fs::PathExt - as this is just a convenience trait, it is not stabilized at
this time.
* fs::set_file_times - this funciton is still waiting on a time abstraction.

|
functionality exposed:
|
|
|
|
|
* `DirEntry` now supports optimizations like `file_type` and `metadata` which
|
|
|
|
|
don't incur a syscall on some platforms.
|
|
|
|
|
* A `symlink_metadata` function has been added.
|
|
|
|
|
* The `fs::Metadata` structure now lowers to its OS counterpart, providing
|
|
|
|
|
access to all underlying information.
|
2015-06-25 15:29:09 +02:00
|
|
|
* The compiler now contains extended explanations of many errors. When an error
|
|
|
|
|
with an explanation occurs the compiler suggests using the `--explain` flag
|
|
|
|
|
to read the explanation. Error explanations are also [available online][err-index].
|
2015-06-11 03:59:55 +02:00
|
|
|
* Thanks to multiple [improvements][sk] to [type checking][pre], as
|
|
|
|
|
well as other work, the time to bootstrap the compiler decreased by
|
|
|
|
|
32%.

* On both Windows and Unix, new extension traits provide conversion of
|
|
|
|
|
I/O types to and from the underlying system handles. On Unix, these
|
2015-06-25 17:41:48 +02:00
|
|
|
traits are [`FromRawFd`] and [`AsRawFd`], on Windows `FromRawHandle`
|
2015-06-11 03:59:55 +02:00
|
|
|
and `AsRawHandle`. These are implemented for `File`, `TcpStream`,
|
|
|
|
|
`TcpListener`, and `UpdSocket`. Further implementations for
|
|
|
|
|
`std::process` will be stabilized later.
|
|
|
|
|
* On Unix, [`std::os::unix::symlink`] creates symlinks. On
|
|
|
|
|
Windows, symlinks can be created with
|
|
|
|
|
`std::os::windows::symlink_dir` and
|
|
|
|
|
`std::os::windows::symlink_file`.
|
|
|
|
|
* The `mpsc::Receiver` type can now be converted into an iterator with
|
|
|
|
|
`into_iter` on the [`IntoIterator`] trait.
|
|
|
|
|
* `Ipv4Addr` can be created from `u32` with the `From<u32>`
|
|
|
|
|
implementation of the [`From`] trait.
|
|
|
|
|
* The `Debug` implementation for `RangeFull` [creates output that is
|
|
|
|
|
more consistent with other implementations][rf].
|
|
|
|
|
* [`Debug` is implemented for `File`][file].
|
|
|
|
|
* The `Default` implementation for `Arc` [no longer requires `Sync +
|
|
|
|
|
Send`][arc].
|
|
|
|
|
* [The `Iterator` methods `count`, `nth`, and `last` have been
|
|
|
|
|
overridden for slices to have O(1) performance instead of O(n)][si].
|
|
|
|
|
* Incorrect handling of paths on Windows has been improved in both the
|
|
|
|
|
compiler and the standard library.
|
|
|
|
|
* [`AtomicPtr` gained a `Default` implementation][ap].
|
|
|
|
|
* In accordance with Rust's policy on arithmetic overflow `abs` now
|
|
|
|
|
[panics on overflow when debug assertions are enabled][abs].
|
|
|
|
|
* The [`Cloned`] iterator, which was accidentally left unstable for
|
|
|
|
|
1.0 [has been stabilized][c].
|
|
|
|
|
* The [`Incoming`] iterator, which iterates over incoming TCP
|
|
|
|
|
connections, and which was accidentally unnamable in 1.0, [is now
|
|
|
|
|
properly exported][inc].
|
|
|
|
|
* [`BinaryHeap`] no longer corrupts itself [when functions called by
|
|
|
|
|
`sift_up` or `sift_down` panic][bh].
|
|
|
|
|
* The [`split_off`] method of `LinkedList` [no longer corrupts
|
|
|
|
|
the list in certain scenarios][ll].

std: Stabilize a number of new fs features
This commit stabilizes the following APIs, slating them all to be cherry-picked
into the 1.1 release.
* fs::FileType (and transitively the derived trait implementations)
* fs::Metadata::file_type
* fs::FileType::is_dir
* fs::FileType::is_file
* fs::FileType::is_symlink
* fs::DirEntry::metadata
* fs::DirEntry::file_type
* fs::DirEntry::file_name
* fs::set_permissions
* fs::symlink_metadata
* os::raw::{self, *}
* os::{android, bitrig, linux, ...}::raw::{self, *}
* os::{android, bitrig, linux, ...}::fs::MetadataExt
* os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat
* os::unix::fs::PermissionsExt
* os::unix::fs::PermissionsExt::mode
* os::unix::fs::PermissionsExt::set_mode
* os::unix::fs::PermissionsExt::from_mode
* os::unix::fs::OpenOptionsExt
* os::unix::fs::OpenOptionsExt::mode
* os::unix::fs::DirEntryExt
* os::unix::fs::DirEntryExt::ino
* os::windows::fs::MetadataExt
* os::windows::fs::MetadataExt::file_attributes
* os::windows::fs::MetadataExt::creation_time
* os::windows::fs::MetadataExt::last_access_time
* os::windows::fs::MetadataExt::last_write_time
* os::windows::fs::MetadataExt::file_size
The `os::unix::fs::Metadata` structure was also removed entirely, moving all of
its associated methods into the `os::unix::fs::MetadataExt` trait instead. The
methods are all marked as `#[stable]` still.
As some minor cleanup, some deprecated and unstable fs apis were also removed:
* File::path
* Metadata::accessed
* Metadata::modified
Features that were explicitly left unstable include:
* fs::WalkDir - the semantics of this were not considered in the recent fs
expansion RFC.
* fs::DirBuilder - it's still not 100% clear if the naming is right here and if
the set of functionality exposed is appropriate.
* fs::canonicalize - the implementation on Windows here is specifically in
question as it always returns a verbatim path. Additionally the Unix
implementation is susceptible to buffer overflows on long paths unfortunately.
* fs::PathExt - as this is just a convenience trait, it is not stabilized at
this time.
* fs::set_file_times - this funciton is still waiting on a time abstraction.

|
* The vast majority of the standard library is now `#[stable]`. It is
|
|
|
|
|
no longer possible to use unstable features with a stable build of
|
|
|
|
|
the compiler.
|
|
|
|
|
* Many popular crates on [crates.io] now work on the stable release
|
|
|
|
|
channel.
|
|
|
|
|
* Arithmetic on basic integer types now [checks for overflow in debug
|
|
|
|
|
builds][overflow].

|
|
|
|
2015-05-06 22:23:33 +02:00
|
|
|
* Several [restrictions have been added to trait coherence][coh] in
|
|
|
|
|
order to make it easier for upstream authors to change traits
|
2015-05-20 02:34:14 +02:00
|
|
|
without breaking downstream code.
|
2015-05-06 22:23:33 +02:00
|
|
|
* Digits of binary and octal literals are [lexed more eagerly][lex] to
|
|
|
|
|
improve error messages and macro behavior. For example, `0b1234` is
|
|
|
|
|
now lexed as `0b1234` instead of two tokens, `0b1` and `234`.
|
2015-05-18 02:09:11 +02:00
|
|
|
* Trait bounds [are always invariant][inv], eliminating the need for
|
2015-05-06 22:23:33 +02:00
|
|
|
the `PhantomFn` and `MarkerTrait` lang items, which have been
|
|
|
|
|
removed.
|
|
|
|
|
* ["-" is no longer a valid character in crate names][cr], the `extern crate
|
|
|
|
|
"foo" as bar` syntax has been replaced with `extern crate foo as
|
|
|
|
|
bar`, and Cargo now automatically translates "-" in *package* names
|
|
|
|
|
to underscore for the crate name.
|
|
|
|
|
* [Lifetime shadowing is an error][lt].
|
|
|
|
|
* [`Send` no longer implies `'static`][send-rfc].
|
|
|
|
|
* [UFCS now supports trait-less associated paths][moar-ufcs] like
|
|
|
|
|
`MyType::default()`.
|
|
|
|
|
* Primitive types [now have inherent methods][prim-inherent],
|
|
|
|
|
obviating the need for extension traits like `SliceExt`.
|
|
|
|
|
* Methods with `Self: Sized` in their `where` clause are [considered
|
|
|
|
|
object-safe][self-sized], allowing many extension traits like
|
|
|
|
|
`IteratorExt` to be merged into the traits they extended.
|
|
|
|
|
* You can now [refer to associated types][assoc-where] whose
|
|
|
|
|
corresponding trait bounds appear only in a `where` clause.
|
|
|
|
|
* The final bits of [OIBIT landed][oibit-final], meaning that traits
|
|
|
|
|
like `Send` and `Sync` are now library-defined.
|
|
|
|
|
* A [Reflect trait][reflect] was introduced, which means that
|
|
|
|
|
downcasting via the `Any` trait is effectively limited to concrete
|
|
|
|
|
types. This helps retain the potentially-important "parametricity"
|
|
|
|
|
property: generic code cannot behave differently for different type
|
|
|
|
|
arguments except in minor ways.
|
|
|
|
|
* The `unsafe_destructor` feature is now deprecated in favor of the
|
|
|
|
|
[new `dropck`][dropck]. This change is a major reduction in unsafe
|
|
|
|
|
code.

2015-05-06 22:23:33 +02:00
|
|
|
* The `thread_local` module [has been renamed to `std::thread`][th].
|
|
|
|
|
* The methods of `IteratorExt` [have been moved to the `Iterator`
|
|
|
|
|
trait itself][ie].
|
|
|
|
|
* Several traits that implement Rust's conventions for type
|
|
|
|
|
conversions, `AsMut`, `AsRef`, `From`, and `Into` have been
|
|
|
|
|
[centralized in the `std::convert` module][con].
|
|
|
|
|
* The `FromError` trait [was removed in favor of `From`][fe].
|
|
|
|
|
* The basic sleep function [has moved to
|
|
|
|
|
`std::thread::sleep_ms`][slp].
|
|
|
|
|
* The `splitn` function now takes an `n` parameter that represents the
|
|
|
|
|
number of items yielded by the returned iterator [instead of the
|
|
|
|
|
number of 'splits'][spl].
|
|
|
|
|
* [On Unix, all file descriptors are `CLOEXEC` by default][clo].
|
|
|
|
|
* [Derived implementations of `PartialOrd` now order enums according
|
|
|
|
|
to their explicitly-assigned discriminants][po].
|
|
|
|
|
* [Methods for searching strings are generic over `Pattern`s][pat],
|
|
|
|
|
implemented presently by `&char`, `&str`, `FnMut(char) -> bool` and
|
|
|
|
|
some others.
|
|
|
|
|
* [In method resolution, object methods are resolved before inherent
|
|
|
|
|
methods][meth].
|
|
|
|
|
* [`String::from_str` has been deprecated in favor of the `From` impl,
|
|
|
|
|
`String::from`][sf].
|
|
|
|
|
* [`io::Error` implements `Sync`][ios].
|
|
|
|
|
* [The `words` method on `&str` has been replaced with
|
|
|
|
|
`split_whitespace`][sw], to avoid answering the tricky question, 'what is
|
|
|
|
|
a word?'
|
|
|
|
|
* The new path and IO modules are complete and `#[stable]`. This
|
|
|
|
|
was the major library focus for this cycle.
|
|
|
|
|
* The path API was [revised][path-normalize] to normalize `.`,
|
|
|
|
|
adjusting the tradeoffs in favor of the most common usage.
|
|
|
|
|
* A large number of remaining APIs in `std` were also stabilized
|
|
|
|
|
during this cycle; about 75% of the non-deprecated API surface
|
|
|
|
|
is now stable.
|
|
|
|
|
* The new [string pattern API][string-pattern] landed, which makes
|
|
|
|
|
the string slice API much more internally consistent and flexible.
|
|
|
|
|
* A new set of [generic conversion traits][conversion] replaced
|
|
|
|
|
many existing ad hoc traits.
|
|
|
|
|
* Generic numeric traits were [completely removed][num-traits]. This
|
|
|
|
|
was made possible thanks to inherent methods for primitive types,
|
|
|
|
|
and the removal gives maximal flexibility for designing a numeric
|
|
|
|
|
hierarchy in the future.
|
|
|
|
|
* The `Fn` traits are now related via [inheritance][fn-inherit]
|
|
|
|
|
and provide ergonomic [blanket implementations][fn-blanket].
|
|
|
|
|
* The `Index` and `IndexMut` traits were changed to
|
|
|
|
|
[take the index by value][index-value], enabling code like
|
|
|
|
|
`hash_map["string"]` to work.
|
|
|
|
|
* `Copy` now [inherits][copy-clone] from `Clone`, meaning that all
|
|
|
|
|
`Copy` data is known to be `Clone` as well.

|
|
|
* rustdoc has received a number of improvements focused on completion
|
|
|
|
|
and polish.
|
|
|
|
|
* Metadata was tuned, shrinking binaries [by 27%][metadata-shrink].
|
|
|
|
|
* Much headway was made on ecosystem-wide CI, making it possible
|
|
|
|
|
to [compare builds for breakage][ci-compare].

Version 1.0.0-alpha.2 (2015-02-20)
|
2015-05-18 09:57:58 +02:00
|
|
|
=====================================
|
2015-02-19 02:02:34 +01:00
|
|
|
|
|
|
|
|
* ~1300 changes, numerous bugfixes
|
|
|
|
|
|
|
|
|
|
* Highlights
|
|
|
|
|
|
|
|
|
|
* The various I/O modules were [overhauled][io-rfc] to reduce
|
2015-05-20 02:34:14 +02:00
|
|
|
unnecessary abstractions and provide better interoperation with
|
2015-02-19 02:02:34 +01:00
|
|
|
the underlying platform. The old `io` module remains temporarily
|
|
|
|
|
at `std::old_io`.
|
2015-05-20 02:34:14 +02:00
|
|
|
* The standard library now [participates in feature gating][feat],
|
2015-02-19 02:02:34 +01:00
|
|
|
so use of unstable libraries now requires a `#![feature(...)]`
|
|
|
|
|
attribute. The impact of this change is [described on the
|
|
|
|
|
forum][feat-forum]. [RFC][feat-rfc].
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
|
|
|
|
|
* `for` loops [now operate on the `IntoIterator` trait][into],
|
|
|
|
|
which eliminates the need to call `.iter()`, etc. to iterate
|
|
|
|
|
over collections. There are some new subtleties to remember
|
|
|
|
|
though regarding what sort of iterators various types yield, in
|
|
|
|
|
particular that `for foo in bar { }` yields values from a move
|
|
|
|
|
iterator, destroying the original collection. [RFC][into-rfc].
|
|
|
|
|
* Objects now have [default lifetime bounds][obj], so you don't
|
|
|
|
|
have to write `Box<Trait+'static>` when you don't care about
|
|
|
|
|
storing references. [RFC][obj-rfc].
|
|
|
|
|
* In types that implement `Drop`, [lifetimes must outlive the
|
|
|
|
|
value][drop]. This will soon make it possible to safely
|
|
|
|
|
implement `Drop` for types where `#[unsafe_destructor]` is now
|
|
|
|
|
required. Read the [gorgeous RFC][drop-rfc] for details.
|
|
|
|
|
* The fully qualified <T as Trait>::X syntax lets you set the Self
|
|
|
|
|
type for a trait method or associated type. [RFC][ufcs-rfc].
|
|
|
|
|
* References to types that implement `Deref<U>` now [automatically
|
|
|
|
|
coerce to references][deref] to the dereferenced type `U`,
|
|
|
|
|
e.g. `&T where T: Deref<U>` automatically coerces to `&U`. This
|
|
|
|
|
should eliminate many unsightly uses of `&*`, as when converting
|
|
|
|
|
from references to vectors into references to
|
|
|
|
|
slices. [RFC][deref-rfc].
|
|
|
|
|
* The explicit [closure kind syntax][close] (`|&:|`, `|&mut:|`,
|
|
|
|
|
`|:|`) is obsolete and closure kind is inferred from context.
|
|
|
|
|
* [`Self` is a keyword][Self].
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
|
|
|
|
|
* The `Show` and `String` formatting traits [have been
|
|
|
|
|
renamed][fmt] to `Debug` and `Display` to more clearly reflect
|
|
|
|
|
their related purposes. Automatically getting a string
|
|
|
|
|
conversion to use with `format!("{:?}", something_to_debug)` is
|
|
|
|
|
now written `#[derive(Debug)]`.
|
|
|
|
|
* Abstract [OS-specific string types][osstr], `std::ff::{OsString,
|
|
|
|
|
OsStr}`, provide strings in platform-specific encodings for easier
|
|
|
|
|
interop with system APIs. [RFC][osstr-rfc].
|
2015-02-21 13:14:17 +01:00
|
|
|
* The `boxed::into_raw` and `Box::from_raw` functions [convert
|
2015-02-19 02:02:34 +01:00
|
|
|
between `Box<T>` and `*mut T`][boxraw], a common pattern for
|
|
|
|
|
creating raw pointers.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
|
|
|
|
|
* Certain long error messages of the form 'expected foo found bar'
|
|
|
|
|
are now [split neatly across multiple
|
|
|
|
|
lines][multiline]. Examples in the PR.
|
|
|
|
|
* On Unix Rust can be [uninstalled][un] by running
|
|
|
|
|
`/usr/local/lib/rustlib/uninstall.sh`.
|
|
|
|
|
* The `#[rustc_on_unimplemented]` attribute, requiring the
|
|
|
|
|
'on_unimplemented' feature, lets rustc [display custom error
|
|
|
|
|
messages when a trait is expected to be implemented for a type
|
|
|
|
|
but is not][onun].
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
|
|
|
|
|
* Rust is tested against a [LALR grammar][lalr], which parses
|
|
|
|
|
almost all the Rust files that rustc does.

Version 1.0.0-alpha (2015-01-09)

2015-05-18 09:57:58 +02:00
|
|
|
==================================
|
2015-01-06 08:41:12 +01:00
|
|
|
|
2015-01-07 01:37:38 +01:00
|
|
|
* ~2400 changes, numerous bugfixes
|
2015-01-06 08:41:12 +01:00
|
|
|
|
|
|
|
|
* Highlights
|
|
|
|
|
|
|
|
|
|
* The language itself is considered feature complete for 1.0,
|
2015-01-07 05:53:55 +01:00
|
|
|
though there will be many usability improvements and bugfixes
|
|
|
|
|
before the final release.
|
2015-01-06 08:41:12 +01:00
|
|
|
* Nearly 50% of the public API surface of the standard library has
|
2015-01-07 01:50:54 +01:00
|
|
|
been declared 'stable'. Those interfaces are unlikely to change
|
|
|
|
|
before 1.0.
|
2015-01-07 05:53:55 +01:00
|
|
|
* The long-running debate over integer types has been
|
|
|
|
|
[settled][ints]: Rust will ship with types named `isize` and
|
|
|
|
|
`usize`, rather than `int` and `uint`, for pointer-sized
|
|
|
|
|
integers. Guidelines will be rolled out during the alpha cycle.
|
2015-01-06 08:41:12 +01:00
|
|
|
* Most crates that are not `std` have been moved out of the Rust
|
|
|
|
|
distribution into the Cargo ecosystem so they can evolve
|
|
|
|
|
separately and don't need to be stabilized as quickly, including
|
|
|
|
|
'time', 'getopts', 'num', 'regex', and 'term'.
|
2014-12-02 15:20:48 +01:00
|
|
|
* Documentation continues to be expanded with more API coverage, more
|
|
|
|
|
examples, and more in-depth explanations. The guides have been
|
|
|
|
|
consolidated into [The Rust Programming Language][trpl].
|
2015-01-09 08:25:42 +01:00
|
|
|
* "[Rust By Example][rbe]" is now maintained by the Rust team.
|
2015-01-06 08:41:12 +01:00
|
|
|
* All official Rust binary installers now come with [Cargo], the
|
|
|
|
|
Rust package manager.
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
|
|
|
|
|
* Closures have been [completely redesigned][unboxed] to be
|
|
|
|
|
implemented in terms of traits, can now be used as generic type
|
|
|
|
|
bounds and thus monomorphized and inlined, or via an opaque
|
|
|
|
|
pointer (boxed) as in the old system. The new system is often
|
|
|
|
|
referred to as 'unboxed' closures.
|
2015-01-06 13:19:01 +01:00
|
|
|
* Traits now support [associated types][assoc], allowing families
|
|
|
|
|
of related types to be defined together and used generically in
|
|
|
|
|
powerful ways.
|
2015-01-06 08:41:12 +01:00
|
|
|
* Enum variants are [namespaced by their type names][enum].
|
|
|
|
|
* [`where` clauses][where] provide a more versatile and attractive
|
|
|
|
|
syntax for specifying generic bounds, though the previous syntax
|
|
|
|
|
remains valid.
|
2015-01-06 13:19:01 +01:00
|
|
|
* Rust again picks a [fallback][fb] (either i32 or f64) for uninferred
|
2015-01-06 08:41:12 +01:00
|
|
|
numeric types.
|
|
|
|
|
* Rust [no longer has a runtime][rt] of any description, and only
|
|
|
|
|
supports OS threads, not green threads.
|
|
|
|
|
* At long last, Rust has been overhauled for 'dynamically-sized
|
|
|
|
|
types' ([DST]), which integrates 'fat pointers' (object types,
|
|
|
|
|
arrays, and `str`) more deeply into the type system, making it
|
|
|
|
|
more consistent.
|
|
|
|
|
* Rust now has a general [range syntax][range], `i..j`, `i..`, and
|
|
|
|
|
`..j` that produce range types and which, when combined with the
|
2015-01-06 13:19:01 +01:00
|
|
|
`Index` operator and multidispatch, leads to a convenient slice
|
2015-01-06 08:41:12 +01:00
|
|
|
notation, `[i..j]`.
|
|
|
|
|
* The new range syntax revealed an ambiguity in the fixed-length
|
|
|
|
|
array syntax, so now fixed length arrays [are written `[T;
|
|
|
|
|
N]`][arrays].
|
|
|
|
|
* The `Copy` trait is no longer implemented automatically. Unsafe
|
|
|
|
|
pointers no longer implement `Sync` and `Send` so types
|
|
|
|
|
containing them don't automatically either. `Sync` and `Send`
|
|
|
|
|
are now 'unsafe traits' so one can "forcibly" implement them via
|
|
|
|
|
`unsafe impl` if a type confirms to the requirements for them
|
|
|
|
|
even though the internals do not (e.g. structs containing unsafe
|
|
|
|
|
pointers like `Arc`). These changes are intended to prevent some
|
|
|
|
|
footguns and are collectively known as [opt-in built-in
|
2015-01-07 07:16:34 +01:00
|
|
|
traits][oibit] (though `Sync` and `Send` will soon become pure
|
2015-01-06 08:41:12 +01:00
|
|
|
library types unknown to the compiler).
|
|
|
|
|
* Operator traits now take their operands [by value][ops], and
|
|
|
|
|
comparison traits can use multidispatch to compare one type
|
|
|
|
|
against multiple other types, allowing e.g. `String` to be
|
|
|
|
|
compared with `&str`.
|
|
|
|
|
* `if let` and `while let` are no longer feature-gated.
|
|
|
|
|
* Rust has adopted a more [uniform syntax for escaping unicode
|
|
|
|
|
characters][unicode].
|
|
|
|
|
* `macro_rules!` [has been declared stable][mac]. Though it is a
|
|
|
|
|
flawed system it is sufficiently popular that it must be usable
|
2015-01-07 01:44:17 +01:00
|
|
|
for 1.0. Effort has gone into [future-proofing][mac-future] it
|
|
|
|
|
in ways that will allow other macro systems to be developed in
|
|
|
|
|
parallel, and won't otherwise impact the evolution of the
|
|
|
|
|
language.
|
2015-01-06 08:41:12 +01:00
|
|
|
* The prelude has been [pared back significantly][prelude] such
|
|
|
|
|
that it is the minimum necessary to support the most pervasive
|
|
|
|
|
code patterns, and through [generalized where clauses][where]
|
|
|
|
|
many of the prelude extension traits have been consolidated.
|
|
|
|
|
* Rust's rudimentary reflection [has been removed][refl], as it
|
|
|
|
|
incurred too much code generation for little benefit.
|
|
|
|
|
* [Struct variants][structvars] are no longer feature-gated.
|
|
|
|
|
* Trait bounds can be [polymorphic over lifetimes][hrtb]. Also
|
|
|
|
|
known as 'higher-ranked trait bounds', this crucially allows
|
|
|
|
|
unboxed closures to work.
|
|
|
|
|
* Macros invocations surrounded by parens or square brackets and
|
|
|
|
|
not terminated by a semicolon are [parsed as
|
|
|
|
|
expressions][macros], which makes expressions like `vec![1i32,
|
|
|
|
|
2, 3].len()` work as expected.
|
2015-01-06 13:19:01 +01:00
|
|
|
* Trait objects now implement their traits automatically, and
|
|
|
|
|
traits that can be coerced to objects now must be [object
|
|
|
|
|
safe][objsafe].
|
2015-01-06 08:41:12 +01:00
|
|
|
* Automatically deriving traits is now done with `#[derive(...)]`
|
|
|
|
|
not `#[deriving(...)]` for [consistency with other naming
|
|
|
|
|
conventions][derive].
|
2015-01-06 13:19:01 +01:00
|
|
|
* Importing the containing module or enum at the same time as
|
|
|
|
|
items or variants they contain is [now done with `self` instead
|
|
|
|
|
of `mod`][self], as in use `foo::{self, bar}`
|
2015-01-07 01:37:38 +01:00
|
|
|
* Glob imports are no longer feature-gated.
|
2015-01-07 01:44:17 +01:00
|
|
|
* The `box` operator and `box` patterns have been feature-gated
|
|
|
|
|
pending a redesign. For now unique boxes should be allocated
|
|
|
|
|
like other containers, with `Box::new`.
|
2015-01-06 08:41:12 +01:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
|
|
|
|
|
* A [series][coll1] of [efforts][coll2] to establish
|
|
|
|
|
[conventions][coll3] for collections types has resulted in API
|
|
|
|
|
improvements throughout the standard library.
|
|
|
|
|
* New [APIs for error handling][err] provide ergonomic interop
|
|
|
|
|
between error types, and [new conventions][err-conv] describe
|
|
|
|
|
more clearly the recommended error handling strategies in Rust.
|
|
|
|
|
* The `fail!` macro has been renamed to [`panic!`][panic] so that
|
|
|
|
|
it is easier to discuss failure in the context of error handling
|
|
|
|
|
without making clarifications as to whether you are referring to
|
|
|
|
|
the 'fail' macro or failure more generally.
|
2015-01-06 13:19:01 +01:00
|
|
|
* On Linux, `OsRng` prefers the new, more reliable `getrandom`
|
2015-01-06 08:41:12 +01:00
|
|
|
syscall when available.
|
|
|
|
|
* The 'serialize' crate has been renamed 'rustc-serialize' and
|
|
|
|
|
moved out of the distribution to Cargo. Although it is widely
|
2015-05-20 02:34:14 +02:00
|
|
|
used now, it is expected to be superseded in the near future.
|
2015-01-06 08:41:12 +01:00
|
|
|
* The `Show` formatter, typically implemented with
|
|
|
|
|
`#[derive(Show)]` is [now requested with the `{:?}`
|
|
|
|
|
specifier][show] and is intended for use by all types, for uses
|
|
|
|
|
such as `println!` debugging. The new `String` formatter must be
|
|
|
|
|
implemented by hand, uses the `{}` specifier, and is intended
|
|
|
|
|
for full-fidelity conversions of things that can logically be
|
|
|
|
|
represented as strings.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
|
|
|
|
|
* [Flexible target specification][flex] allows rustc's code
|
|
|
|
|
generation to be configured to support otherwise-unsupported
|
|
|
|
|
platforms.
|
|
|
|
|
* Rust comes with rust-gdb and rust-lldb scripts that launch their
|
|
|
|
|
respective debuggers with Rust-appropriate pretty-printing.
|
2017-01-17 09:18:45 +01:00
|
|
|
* The Windows installation of Rust is distributed with the
|
2015-01-06 08:41:12 +01:00
|
|
|
MinGW components currently required to link binaries on that
|
|
|
|
|
platform.
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
|
|
|
|
|
* Nullable enum optimizations have been extended to more types so
|
|
|
|
|
that e.g. `Option<Vec<T>>` and `Option<String>` take up no more
|
|
|
|
|
space than the inner types themselves.
|
|
|
|
|
* Work has begun on supporting AArch64.

=============================
|
2014-10-03 00:54:43 +02:00
|
|
|
|
2014-10-06 21:07:28 +02:00
|
|
|
* ~1900 changes, numerous bugfixes
|
2014-10-03 00:54:43 +02:00
|
|
|
|
|
|
|
|
* Highlights
|
|
|
|
|
|
|
|
|
|
* The introductory documentation (now called The Rust Guide) has
|
|
|
|
|
been completely rewritten, as have a number of supplementary
|
|
|
|
|
guides.
|
2014-10-07 02:30:30 +02:00
|
|
|
* Rust's package manager, Cargo, continues to improve and is
|
|
|
|
|
sometimes considered to be quite awesome.
|
2014-10-03 00:54:43 +02:00
|
|
|
* Many API's in `std` have been reviewed and updated for
|
|
|
|
|
consistency with the in-development Rust coding
|
|
|
|
|
guidelines. The standard library documentation tracks
|
|
|
|
|
stabilization progress.
|
|
|
|
|
* Minor libraries have been moved out-of-tree to the rust-lang org
|
|
|
|
|
on GitHub: uuid, semver, glob, num, hexfloat, fourcc. They can
|
|
|
|
|
be installed with Cargo.
|
|
|
|
|
* Lifetime elision allows lifetime annotations to be left off of
|
|
|
|
|
function declarations in many common scenarios.
|
|
|
|
|
* Rust now works on 64-bit Windows.
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* Indexing can be overloaded with the `Index` and `IndexMut`
|
|
|
|
|
traits.
|
|
|
|
|
* The `if let` construct takes a branch only if the `let` pattern
|
|
|
|
|
matches, currently behind the 'if_let' feature gate.
|
2014-10-06 21:07:28 +02:00
|
|
|
* 'where clauses', a more flexible syntax for specifying trait
|
|
|
|
|
bounds that is more aesthetic, have been added for traits and
|
|
|
|
|
free functions. Where clauses will in the future make it
|
|
|
|
|
possible to constrain associated types, which would be
|
|
|
|
|
impossible with the existing syntax.
|
|
|
|
|
* A new slicing syntax (e.g. `[0..4]`) has been introduced behind
|
|
|
|
|
the 'slicing_syntax' feature gate, and can be overloaded with
|
2014-10-07 02:30:30 +02:00
|
|
|
the `Slice` or `SliceMut` traits.
|
2014-10-06 21:07:28 +02:00
|
|
|
* The syntax for matching of sub-slices has been changed to use a
|
|
|
|
|
postfix `..` instead of prefix (.e.g. `[a, b, c..]`), for
|
|
|
|
|
consistency with other uses of `..` and to future-proof
|
|
|
|
|
potential additional uses of the syntax.
|
|
|
|
|
* The syntax for matching inclusive ranges in patterns has changed
|
|
|
|
|
from `0..3` to `0...4` to be consistent with the exclusive range
|
|
|
|
|
syntax for slicing.
|
|
|
|
|
* Matching of sub-slices in non-tail positions (e.g. `[a.., b,
|
|
|
|
|
c]`) has been put behind the 'advanced_slice_patterns' feature
|
|
|
|
|
gate and may be removed in the future.
|
|
|
|
|
* Components of tuples and tuple structs can be extracted using
|
|
|
|
|
the `value.0` syntax, currently behind the `tuple_indexing`
|
|
|
|
|
feature gate.
|
2014-10-03 00:54:43 +02:00
|
|
|
* The `#[crate_id]` attribute is no longer supported; versioning
|
|
|
|
|
is handled by the package manager.
|
2014-10-06 21:07:28 +02:00
|
|
|
* Renaming crate imports are now written `extern crate foo as bar`
|
|
|
|
|
instead of `extern crate bar = foo`.
|
|
|
|
|
* Renaming use statements are now written `use foo as bar` instead
|
|
|
|
|
of `use bar = foo`.
|
|
|
|
|
* `let` and `match` bindings and argument names in macros are now
|
|
|
|
|
hygienic.
|
2014-10-03 00:54:43 +02:00
|
|
|
* The new, more efficient, closure types ('unboxed closures') have
|
|
|
|
|
been added under a feature gate, 'unboxed_closures'. These will
|
|
|
|
|
soon replace the existing closure types, once higher-ranked
|
|
|
|
|
trait lifetimes are added to the language.
|
2014-10-06 21:07:28 +02:00
|
|
|
* `move` has been added as a keyword, for indicating closures
|
|
|
|
|
that capture by value.
|
|
|
|
|
* Mutation and assignment is no longer allowed in pattern guards.
|
|
|
|
|
* Generic structs and enums can now have trait bounds.
|
2014-10-03 00:54:43 +02:00
|
|
|
* The `Share` trait is now called `Sync` to free up the term
|
|
|
|
|
'shared' to refer to 'shared reference' (the default reference
|
|
|
|
|
type.
|
|
|
|
|
* Dynamically-sized types have been mostly implemented,
|
|
|
|
|
unifying the behavior of fat-pointer types with the rest of the
|
|
|
|
|
type system.
|
|
|
|
|
* As part of dynamically-sized types, the `Sized` trait has been
|
|
|
|
|
introduced, which qualifying types implement by default, and
|
|
|
|
|
which type parameters expect by default. To specify that a type
|
2014-10-06 21:07:28 +02:00
|
|
|
parameter does not need to be sized, write `<Sized? T>`. Most
|
2014-10-03 00:54:43 +02:00
|
|
|
types are `Sized`, notable exceptions being unsized arrays
|
|
|
|
|
(`[T]`) and trait types.
|
2014-10-06 21:07:28 +02:00
|
|
|
* Closures can return `!`, as in `|| -> !` or `proc() -> !`.
|
|
|
|
|
* Lifetime bounds can now be applied to type parameters and object
|
|
|
|
|
types.
|
|
|
|
|
* The old, reference counted GC type, `Gc<T>` which was once
|
|
|
|
|
denoted by the `@` sigil, has finally been removed. GC will be
|
|
|
|
|
revisited in the future.
|
2014-10-03 00:54:43 +02:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* Library documentation has been improved for a number of modules.
|
|
|
|
|
* Bit-vectors, collections::bitv has been modernized.
|
|
|
|
|
* The url crate is deprecated in favor of
|
|
|
|
|
http://github.com/servo/rust-url, which can be installed with
|
|
|
|
|
Cargo.
|
2014-10-06 21:07:28 +02:00
|
|
|
* Most I/O stream types can be cloned and subsequently closed from
|
|
|
|
|
a different thread.
|
2014-10-03 00:54:43 +02:00
|
|
|
* A `std::time::Duration` type has been added for use in I/O
|
|
|
|
|
methods that rely on timers, as well as in the 'time' crate's
|
|
|
|
|
`Timespec` arithmetic.
|
2014-10-06 21:07:28 +02:00
|
|
|
* The runtime I/O abstraction layer that enabled the green thread
|
|
|
|
|
scheduler to do non-thread-blocking I/O has been removed, along
|
|
|
|
|
with the libuv-based implementation employed by the green thread
|
|
|
|
|
scheduler. This will greatly simplify the future I/O work.
|
|
|
|
|
* `collections::btree` has been rewritten to have a more
|
|
|
|
|
idiomatic and efficient design.
|
2014-10-03 00:54:43 +02:00
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* rustdoc output now indicates the stability levels of API's.
|
|
|
|
|
* The `--crate-name` flag can specify the name of the crate
|
|
|
|
|
being compiled, like `#[crate_name]`.
|
2014-10-06 21:07:28 +02:00
|
|
|
* The `-C metadata` specifies additional metadata to hash into
|
2014-10-03 00:54:43 +02:00
|
|
|
symbol names, and `-C extra-filename` specifies additional
|
2014-10-06 21:07:28 +02:00
|
|
|
information to put into the output filename, for use by the
|
|
|
|
|
package manager for versioning.
|
2014-10-03 00:54:43 +02:00
|
|
|
* debug info generation has continued to improve and should be
|
|
|
|
|
more reliable under both gdb and lldb.
|
|
|
|
|
* rustc has experimental support for compiling in parallel
|
|
|
|
|
using the `-C codegen-units` flag.
|
|
|
|
|
* rustc no longer encodes rpath information into binaries by
|
|
|
|
|
default.
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
* Stack usage has been optimized with LLVM lifetime annotations.
|
|
|
|
|
* Official Rust binaries on Linux are more compatible with older
|
|
|
|
|
kernels and distributions, built on CentOS 5.10.

==========================
|
2014-06-27 21:46:42 +02:00
|
|
|
|
|
|
|
|
* ~1700 changes, numerous bugfixes
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* ~[T] has been removed from the language. This type is superseded by
|
|
|
|
|
the Vec<T> type.
|
|
|
|
|
* ~str has been removed from the language. This type is superseded by
|
|
|
|
|
the String type.
|
|
|
|
|
* ~T has been removed from the language. This type is superseded by the
|
|
|
|
|
Box<T> type.
|
|
|
|
|
* @T has been removed from the language. This type is superseded by the
|
|
|
|
|
standard library's std::gc::Gc<T> type.
|
|
|
|
|
* Struct fields are now all private by default.
|
|
|
|
|
* Vector indices and shift amounts are both required to be a `uint`
|
|
|
|
|
instead of any integral type.
|
|
|
|
|
* Byte character, byte string, and raw byte string literals are now all
|
|
|
|
|
supported by prefixing the normal literal with a `b`.
|
|
|
|
|
* Multiple ABIs are no longer allowed in an ABI string
|
|
|
|
|
* The syntax for lifetimes on closures/procedures has been tweaked
|
|
|
|
|
slightly: `<'a>|A, B|: 'b + K -> T`
|
|
|
|
|
* Floating point modulus has been removed from the language; however it
|
|
|
|
|
is still provided by a library implementation.
|
|
|
|
|
* Private enum variants are now disallowed.
|
|
|
|
|
* The `priv` keyword has been removed from the language.
|
|
|
|
|
* A closure can no longer be invoked through a &-pointer.
|
|
|
|
|
* The `use foo, bar, baz;` syntax has been removed from the language.
|
|
|
|
|
* The transmute intrinsic no longer works on type parameters.
|
|
|
|
|
* Statics now allow blocks/items in their definition.
|
|
|
|
|
* Trait bounds are separated from objects with + instead of : now.
|
|
|
|
|
* Objects can no longer be read while they are mutably borrowed.
|
|
|
|
|
* The address of a static is now marked as insignificant unless the
|
|
|
|
|
#[inline(never)] attribute is placed it.
|
|
|
|
|
* The #[unsafe_destructor] attribute is now behind a feature gate.
|
|
|
|
|
* Struct literals are no longer allowed in ambiguous positions such as
|
|
|
|
|
if, while, match, and for..in.
|
|
|
|
|
* Declaration of lang items and intrinsics are now feature-gated by
|
|
|
|
|
default.
|
|
|
|
|
* Integral literals no longer default to `int`, and floating point
|
|
|
|
|
literals no longer default to `f64`. Literals must be suffixed with an
|
|
|
|
|
appropriate type if inference cannot determine the type of the
|
|
|
|
|
literal.
|
|
|
|
|
* The Box<T> type is no longer implicitly borrowed to &mut T.
|
|
|
|
|
* Procedures are now required to not capture borrowed references.
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* The standard library is now a "facade" over a number of underlying
|
|
|
|
|
libraries. This means that development on the standard library should
|
2017-11-21 15:33:45 +01:00
|
|
|
be speedier due to smaller crates, as well as a clearer line between
|
2014-06-27 21:46:42 +02:00
|
|
|
all dependencies.
|
|
|
|
|
* A new library, libcore, lives under the standard library's facade
|
|
|
|
|
which is Rust's "0-assumption" library, suitable for embedded and
|
|
|
|
|
kernel development for example.
|
|
|
|
|
* A regex crate has been added to the standard distribution. This crate
|
|
|
|
|
includes statically compiled regular expressions.
|
|
|
|
|
* The unwrap/unwrap_err methods on Result require a Show bound for
|
|
|
|
|
better error messages.
|
|
|
|
|
* The return types of the std::comm primitives have been centralized
|
|
|
|
|
around the Result type.
|
|
|
|
|
* A number of I/O primitives have gained the ability to time out their
|
|
|
|
|
operations.
|
|
|
|
|
* A number of I/O primitives have gained the ability to close their
|
|
|
|
|
reading/writing halves to cancel pending operations.
|
|
|
|
|
* Reverse iterator methods have been removed in favor of `rev()` on
|
|
|
|
|
their forward-iteration counterparts.
|
|
|
|
|
* A bitflags! macro has been added to enable easy interop with C and
|
|
|
|
|
management of bit flags.
|
|
|
|
|
* A debug_assert! macro is now provided which is disabled when
|
|
|
|
|
`--cfg ndebug` is passed to the compiler.
|
|
|
|
|
* A graphviz crate has been added for creating .dot files.
|
|
|
|
|
* The std::cast module has been migrated into std::mem.
|
|
|
|
|
* The std::local_data api has been migrated from freestanding functions
|
|
|
|
|
to being based on methods.
|
|
|
|
|
* The Pod trait has been renamed to Copy.
|
|
|
|
|
* jemalloc has been added as the default allocator for types.
|
|
|
|
|
* The API for allocating memory has been changed to use proper alignment
|
|
|
|
|
and sized deallocation
|
|
|
|
|
* Connecting a TcpStream or binding a TcpListener is now based on a
|
|
|
|
|
string address and a u16 port. This allows connecting to a hostname as
|
|
|
|
|
opposed to an IP.
|
|
|
|
|
* The Reader trait now contains a core method, read_at_least(), which
|
|
|
|
|
correctly handles many repeated 0-length reads.
|
|
|
|
|
* The process-spawning API is now centered around a builder-style
|
|
|
|
|
Command struct.
|
|
|
|
|
* The :? printing qualifier has been moved from the standard library to
|
|
|
|
|
an external libdebug crate.
|
|
|
|
|
* Eq/Ord have been renamed to PartialEq/PartialOrd. TotalEq/TotalOrd
|
|
|
|
|
have been renamed to Eq/Ord.
|
|
|
|
|
* The select/plural methods have been removed from format!. The escapes
|
|
|
|
|
for { and } have also changed from \{ and \} to {{ and }},
|
|
|
|
|
respectively.
|
|
|
|
|
* The TaskBuilder API has been re-worked to be a true builder, and
|
|
|
|
|
extension traits for spawning native/green tasks have been added.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* All breaking changes to the language or libraries now have their
|
|
|
|
|
commit message annotated with `[breaking-change]` to allow for easy
|
|
|
|
|
discovery of breaking changes.
|
|
|
|
|
* The compiler will now try to suggest how to annotate lifetimes if a
|
|
|
|
|
lifetime-related error occurs.
|
|
|
|
|
* Debug info continues to be improved greatly with general bug fixes and
|
|
|
|
|
better support for situations like link time optimization (LTO).
|
|
|
|
|
* Usage of syntax extensions when cross-compiling has been fixed.
|
|
|
|
|
* Functionality equivalent to GCC & Clang's -ffunction-sections,
|
|
|
|
|
-fdata-sections and --gc-sections has been enabled by default
|
|
|
|
|
* The compiler is now stricter about where it will load module files
|
|
|
|
|
from when a module is declared via `mod foo;`.
|
|
|
|
|
* The #[phase(syntax)] attribute has been renamed to #[phase(plugin)].
|
|
|
|
|
Syntax extensions are now discovered via a "plugin registrar" type
|
|
|
|
|
which will be extended in the future to other various plugins.
|
|
|
|
|
* Lints have been restructured to allow for dynamically loadable lints.
|
|
|
|
|
* A number of rustdoc improvements:
|
|
|
|
|
* The HTML output has been visually redesigned.
|
|
|
|
|
* Markdown is now powered by hoedown instead of sundown.
|
|
|
|
|
* Searching heuristics have been greatly improved.
|
|
|
|
|
* The search index has been reduced in size by a great amount.
|
|
|
|
|
* Cross-crate documentation via `pub use` has been greatly improved.
|
|
|
|
|
* Primitive types are now hyperlinked and documented.
|
|
|
|
|
* Documentation has been moved from static.rust-lang.org/doc to
|
|
|
|
|
doc.rust-lang.org
|
|
|
|
|
* A new sandbox, play.rust-lang.org, is available for running and
|
|
|
|
|
sharing rust code examples on-line.
|
|
|
|
|
* Unused attributes are now more robustly warned about.
|
|
|
|
|
* The dead_code lint now warns about unused struct fields.
|
|
|
|
|
* Cross-compiling to iOS is now supported.
|
|
|
|
|
* Cross-compiling to mipsel is now supported.
|
|
|
|
|
* Stability attributes are now inherited by default and no longer apply
|
|
|
|
|
to intra-crate usage, only inter-crate usage.
|
|
|
|
|
* Error message related to non-exhaustive match expressions have been
|
|
|
|
|
greatly improved.

|
|
|
|
|
|
|
|

|
|
|
|
|

|
|
|
|
|
reference counting have been removed.
|
|
|
|
|
* The semantics around the lifetimes of temporary expressions have changed,
|
|
|
|
|
see #3511 and #11585 for more information.
|
|
|
|
|
* Cross-crate syntax extensions are now possible, but feature gated. See
|
|
|
|
|
#11151 for more information. This includes both `macro_rules!` macros as
|
|
|
|
|
well as syntax extensions such as `format!`.
|
|
|
|
|
* New lint modes have been added, and older ones have been turned on to be
|
|
|
|
|
warn-by-default.
|
|
|
|
|

|
|
|
|
|

|
2014-03-29 01:08:32 +01:00
|
|
|
* Visibility is no longer allowed on `extern crate` statements, and
|
|
|
|
|
unnecessary visibility (`priv`) is no longer allowed on `use` statements.
|
|
|
|
|
* Trailing commas are now allowed in argument lists and tuple patterns.
|
|
|
|
|
* The `do` keyword has been removed, it is now a reserved keyword.
|
|
|
|
|
* Default type parameters have been implemented, but are feature gated.
|
|
|
|
|
* Borrowed variables through captures in closures are now considered soundly.
|
|
|
|
|
* `extern mod` is now `extern crate`
|
|
|
|
|
* The `Freeze` trait has been removed.
|
|
|
|
|
* The `Share` trait has been added for types that can be shared among
|
|
|
|
|
threads.
|
|
|
|
|
* Labels in macros are now hygienic.
|
2014-04-01 13:55:09 +02:00
|
|
|
* Expression/statement macro invocations can be delimited with `{}` now.
|
2014-03-29 01:08:32 +01:00
|
|
|
* Treatment of types allowed in `static mut` locations has been tweaked.
|
|
|
|
|
* The `*` and `.` operators are now overloadable through the `Deref` and
|
|
|
|
|
`DerefMut` traits.
|
|
|
|
|
* `~Trait` and `proc` no longer have `Send` bounds by default.
|
|
|
|
|
* Partial type hints are now supported with the `_` type marker.
|
|
|
|
|
* An `Unsafe` type was introduced for interior mutability. It is now
|
|
|
|
|
considered undefined to transmute from `&T` to `&mut T` without using the
|
|
|
|
|
`Unsafe` type.
|
|
|
|
|
* The #[linkage] attribute was implemented for extern statics/functions.
|
|
|
|
|
* The inner attribute syntax has changed from `#[foo];` to `#![foo]`.
|
|
|
|
|
* `Pod` was renamed to `Copy`.
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* The `libextra` library has been removed. It has now been decomposed into
|
|
|
|
|
component libraries with smaller and more focused nuggets of
|
|
|
|
|
functionality. The full list of libraries can be found on the
|
|
|
|
|
documentation index page.
|
|
|
|
|
* std: `std::condition` has been removed. All I/O errors are now propagated
|
|
|
|
|
through the `Result` type. In order to assist with error handling, a
|
2014-05-02 03:02:11 +02:00
|
|
|
`try!` macro for unwrapping errors with an early return and a lint for
|
2014-03-29 01:08:32 +01:00
|
|
|
unused results has been added. See #12039 for more information.
|
|
|
|
|
* std: The `vec` module has been renamed to `slice`.
|
|
|
|
|
* std: A new vector type, `Vec<T>`, has been added in preparation for DST.
|
|
|
|
|
This will become the only growable vector in the future.
|
2018-01-12 22:41:25 +01:00
|
|
|
* std: `std::io` now has more public re-exports. Types such as `BufferedReader`
|
2014-03-29 01:08:32 +01:00
|
|
|
are now found at `std::io::BufferedReader` instead of
|
|
|
|
|
`std::io::buffered::BufferedReader`.
|
|
|
|
|
* std: `print` and `println` are no longer in the prelude, the `print!` and
|
|
|
|
|
`println!` macros are intended to be used instead.
|
|
|
|
|
* std: `Rc` now has a `Weak` pointer for breaking cycles, and it no longer
|
|
|
|
|
attempts to statically prevent cycles.
|
|
|
|
|
* std: The standard distribution is adopting the policy of pushing failure
|
|
|
|
|
to the user rather than failing in libraries. Many functions (such as
|
|
|
|
|
`slice::last()`) now return `Option<T>` instead of `T` + failing.
|
|
|
|
|
* std: `fmt::Default` has been renamed to `fmt::Show`, and it now has a new
|
|
|
|
|
deriving mode: `#[deriving(Show)]`.
|
|
|
|
|
* std: `ToStr` is now implemented for all types implementing `Show`.
|
|
|
|
|
* std: The formatting trait methods now take `&self` instead of `&T`
|
|
|
|
|
* std: The `invert()` method on iterators has been renamed to `rev()`
|
|
|
|
|
* std: `std::num` has seen a reduction in the genericity of its traits,
|
|
|
|
|
consolidating functionality into a few core traits.
|
|
|
|
|
* std: Backtraces are now printed on task failure if the environment
|
|
|
|
|
variable `RUST_BACKTRACE` is present.
|
|
|
|
|
* std: Naming conventions for iterators have been standardized. More details
|
|
|
|
|
can be found on the wiki's style guide.
|
|
|
|
|
* std: `eof()` has been removed from the `Reader` trait. Specific types may
|
|
|
|
|
still implement the function.
|
|
|
|
|
* std: Networking types are now cloneable to allow simultaneous reads/writes.
|
|
|
|
|
* std: `assert_approx_eq!` has been removed
|
|
|
|
|
* std: The `e` and `E` formatting specifiers for floats have been added to
|
|
|
|
|
print them in exponential notation.
|
|
|
|
|
* std: The `Times` trait has been removed
|
|
|
|
|
* std: Indications of variance and opting out of builtin bounds is done
|
|
|
|
|
through marker types in `std::kinds::marker` now
|
|
|
|
|
* std: `hash` has been rewritten, `IterBytes` has been removed, and
|
|
|
|
|
`#[deriving(Hash)]` is now possible.
|
|
|
|
|
* std: `SharedChan` has been removed, `Sender` is now cloneable.
|
|
|
|
|
* std: `Chan` and `Port` were renamed to `Sender` and `Receiver`.
|
|
|
|
|
* std: `Chan::new` is now `channel()`.
|
|
|
|
|
* std: A new synchronous channel type has been implemented.
|
|
|
|
|
* std: A `select!` macro is now provided for selecting over `Receiver`s.
|
|
|
|
|
* std: `hashmap` and `trie` have been moved to `libcollections`
|
|
|
|
|
* std: `run` has been rolled into `io::process`
|
|
|
|
|
* std: `assert_eq!` now uses `{}` instead of `{:?}`
|
|
|
|
|
* std: The equality and comparison traits have seen some reorganization.
|
|
|
|
|
* std: `rand` has moved to `librand`.
|
|
|
|
|
* std: `to_{lower,upper}case` has been implemented for `char`.
|
|
|
|
|
* std: Logging has been moved to `liblog`.
|
|
|
|
|
* collections: `HashMap` has been rewritten for higher performance and less
|
|
|
|
|
memory usage.
|
|
|
|
|
* native: The default runtime is now `libnative`. If `libgreen` is desired,
|
|
|
|
|
it can be booted manually. The runtime guide has more information and
|
|
|
|
|
examples.
|
|
|
|
|
* native: All I/O functionality except signals has been implemented.
|
|
|
|
|
* green: Task spawning with `libgreen` has been optimized with stack caching
|
|
|
|
|
and various trimming of code.
|
|
|
|
|
* green: Tasks spawned by `libgreen` now have an unmapped guard page.
|
|
|
|
|
* sync: The `extra::sync` module has been updated to modern rust (and moved
|
|
|
|
|
to the `sync` library), tweaking and improving various interfaces while
|
|
|
|
|
dropping redundant functionality.
|
|
|
|
|
* sync: A new `Barrier` type has been added to the `sync` library.
|
|
|
|
|
* sync: An efficient mutex for native and green tasks has been implemented.
|
|
|
|
|
* serialize: The `base64` module has seen some improvement. It treats
|
|
|
|
|
newlines better, has non-string error values, and has seen general
|
|
|
|
|
cleanup.
|
|
|
|
|
* fourcc: A `fourcc!` macro was introduced
|
|
|
|
|
* hexfloat: A `hexfloat!` macro was implemented for specifying floats via a
|
|
|
|
|
hexadecimal literal.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* `rustpkg` has been deprecated and removed from the main repository. Its
|
|
|
|
|
replacement, `cargo`, is under development.
|
2014-04-01 13:55:09 +02:00
|
|
|
* Nightly builds of rust are now available
|
2014-03-29 01:08:32 +01:00
|
|
|
* The memory usage of rustc has been improved many times throughout this
|
|
|
|
|
release cycle.
|
|
|
|
|
* The build process supports disabling rpath support for the rustc binary
|
|
|
|
|
itself.
|
|
|
|
|
* Code generation has improved in some cases, giving more information to the
|
|
|
|
|
LLVM optimization passes to enable more extensive optimizations.
|
|
|
|
|
* Debuginfo compatibility with lldb on OSX has been restored.
|
|
|
|
|
* The master branch is now gated on an android bot, making building for
|
|
|
|
|
android much more reliable.
|
|
|
|
|
* Output flags have been centralized into one `--emit` flag.
|
|
|
|
|
* Crate type flags have been centralized into one `--crate-type` flag.
|
|
|
|
|
* Codegen flags have been consolidated behind a `-C` flag.
|
|
|
|
|
* Linking against outdated crates now has improved error messages.
|
|
|
|
|
* Error messages with lifetimes will often suggest how to annotate the
|
|
|
|
|
function to fix the error.
|
|
|
|
|
* Many more types are documented in the standard library, and new guides
|
|
|
|
|
were written.
|
2014-04-01 13:55:09 +02:00
|
|
|
* Many `rustdoc` improvements:
|
|
|
|
|
* code blocks are syntax highlighted.
|
|
|
|
|
* render standalone markdown files.
|
|
|
|
|
* the --test flag tests all code blocks by default.
|
|
|
|
|
* exported macros are displayed.
|
2018-01-12 22:41:25 +01:00
|
|
|
* re-exported types have their documentation inlined at the location of the
|
|
|
|
|
first re-export.
|
2014-04-01 13:55:09 +02:00
|
|
|
* search works across crates that have been rendered to the same output
|
|

|
|
|
|
2014-01-06 23:50:25 +01:00
|
|
|
* ~1800 changes, numerous bugfixes
|
2013-12-31 23:35:01 +01:00
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* The `float` type has been removed. Use `f32` or `f64` instead.
|
|
|
|
|
* A new facility for enabling experimental features (feature gating) has
|
|
|
|
|
been added, using the crate-level `#[feature(foo)]` attribute.
|
|
|
|
|
* Managed boxes (@) are now behind a feature gate
|
2014-07-05 06:22:59 +02:00
|
|
|
(`#[feature(managed_boxes)]`) in preparation for future removal. Use the
|
2013-12-31 23:35:01 +01:00
|
|
|
standard library's `Gc` or `Rc` types instead.
|
|
|
|
|
* `@mut` has been removed. Use `std::cell::{Cell, RefCell}` instead.
|
|
|
|
|
* Jumping back to the top of a loop is now done with `continue` instead of
|
|
|
|
|
`loop`.
|
|
|
|
|
* Strings can no longer be mutated through index assignment.
|
|
|
|
|
* Raw strings can be created via the basic `r"foo"` syntax or with matched
|
|
|
|
|
hash delimiters, as in `r###"foo"###`.
|
|
|
|
|
* `~fn` is now written `proc (args) -> retval { ... }` and may only be
|
|
|
|
|
called once.
|
|
|
|
|
* The `&fn` type is now written `|args| -> ret` to match the literal form.
|
|
|
|
|
* `@fn`s have been removed.
|
|
|
|
|
* `do` only works with procs in order to make it obvious what the cost
|
|
|
|
|
of `do` is.
|
2014-01-06 23:50:25 +01:00
|
|
|
* Single-element tuple-like structs can no longer be dereferenced to
|
|
|
|
|
obtain the inner value. A more comprehensive solution for overloading
|
|
|
|
|
the dereference operator will be provided in the future.
|
2013-12-31 23:35:01 +01:00
|
|
|
* The `#[link(...)]` attribute has been replaced with
|
|
|
|
|
`#[crate_id = "name#vers"]`.
|
|
|
|
|
* Empty `impl`s must be terminated with empty braces and may not be
|
|
|
|
|
terminated with a semicolon.
|
|
|
|
|
* Keywords are no longer allowed as lifetime names; the `self` lifetime
|
|
|
|
|
no longer has any special meaning.
|
|
|
|
|
* The old `fmt!` string formatting macro has been removed.
|
|
|
|
|
* `printf!` and `printfln!` (old-style formatting) removed in favor of
|
|
|
|
|
`print!` and `println!`.
|
|
|
|
|
* `mut` works in patterns now, as in `let (mut x, y) = (1, 2);`.
|
2014-01-06 23:50:25 +01:00
|
|
|
* The `extern mod foo (name = "bar")` syntax has been removed. Use
|
|
|
|
|
`extern mod foo = "bar"` instead.
|
2013-12-31 23:35:01 +01:00
|
|
|
* New reserved keywords: `alignof`, `offsetof`, `sizeof`.
|
|
|
|
|
* Macros can have attributes.
|
|
|
|
|
* Macros can expand to items with attributes.
|
|
|
|
|
* Macros can expand to multiple items.
|
|
|
|
|
* The `asm!` macro is feature-gated (`#[feature(asm)]`).
|
|
|
|
|
* Comments may be nested.
|
|
|
|
|
* Values automatically coerce to trait objects they implement, without
|
|
|
|
|
an explicit `as`.
|
|
|
|
|
* Enum discriminants are no longer an entire word but as small as needed to
|
|
|
|
|
contain all the variants. The `repr` attribute can be used to override
|
|
|
|
|
the discriminant size, as in `#[repr(int)]` for integer-sized, and
|
|
|
|
|
`#[repr(C)]` to match C enums.
|
|
|
|
|
* Non-string literals are not allowed in attributes (they never worked).
|
|
|
|
|
* The FFI now supports variadic functions.
|
|
|
|
|
* Octal numeric literals, as in `0o7777`.
|
|
|
|
|
* The `concat!` syntax extension performs compile-time string concatenation.
|
|
|
|
|
* The `#[fixed_stack_segment]` and `#[rust_stack]` attributes have been
|
|
|
|
|
removed as Rust no longer uses segmented stacks.
|
|
|
|
|
* Non-ascii identifiers are feature-gated (`#[feature(non_ascii_idents)]`).
|
|
|
|
|
* Ignoring all fields of an enum variant or tuple-struct is done with `..`,
|
|
|
|
|
not `*`; ignoring remaining fields of a struct is also done with `..`,
|
|
|
|
|
not `_`; ignoring a slice of a vector is done with `..`, not `.._`.
|
|
|
|
|
* `rustc` supports the "win64" calling convention via `extern "win64"`.
|
|
|
|
|
* `rustc` supports the "system" calling convention, which defaults to the
|
|
|
|
|
preferred convention for the target platform, "stdcall" on 32-bit Windows,
|
|
|
|
|
"C" elsewhere.
|
|
|
|
|
* The `type_overflow` lint (default: warn) checks literals for overflow.
|
|
|
|
|
* The `unsafe_block` lint (default: allow) checks for usage of `unsafe`.
|
|
|
|
|
* The `attribute_usage` lint (default: warn) warns about unknown
|
|
|
|
|
attributes.
|
|
|
|
|
* The `unknown_features` lint (default: warn) warns about unknown
|
|
|
|
|
feature gates.
|
|
|
|
|
* The `dead_code` lint (default: warn) checks for dead code.
|
|
|
|
|
* Rust libraries can be linked statically to one another
|
|
|
|
|
* `#[link_args]` is behind the `link_args` feature gate.
|
|
|
|
|
* Native libraries are now linked with `#[link(name = "foo")]`
|
|
|
|
|
* Native libraries can be statically linked to a rust crate
|
|
|
|
|
(`#[link(name = "foo", kind = "static")]`).
|
|
|
|
|
* Native OS X frameworks are now officially supported
|
|
|
|
|
(`#[link(name = "foo", kind = "framework")]`).
|
|
|
|
|
* The `#[thread_local]` attribute creates thread-local (not task-local)
|
|
|
|
|
variables. Currently behind the `thread_local` feature gate.
|
|
|
|
|
* The `return` keyword may be used in closures.
|
|
|
|
|
* Types that can be copied via a memcpy implement the `Pod` kind.
|
2014-01-06 23:50:25 +01:00
|
|
|
* The `cfg` attribute can now be used on struct fields and enum variants.
|
2013-12-31 23:35:01 +01:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* std: The `option` and `result` API's have been overhauled to make them
|
|
|
|
|
simpler, more consistent, and more composable.
|
|
|
|
|
* std: The entire `std::io` module has been replaced with one that is
|
|
|
|
|
more comprehensive and that properly interfaces with the underlying
|
|
|
|
|
scheduler. File, TCP, UDP, Unix sockets, pipes, and timers are all
|
|
|
|
|
implemented.
|
|
|
|
|
* std: `io::util` contains a number of useful implementations of
|
|
|
|
|
`Reader` and `Writer`, including `NullReader`, `NullWriter`,
|
|
|
|
|
`ZeroReader`, `TeeReader`.
|
|
|
|
|
* std: The reference counted pointer type `extra::rc` moved into std.
|
|
|
|
|
* std: The `Gc` type in the `gc` module will replace `@` (it is currently
|
|
|
|
|
just a wrapper around it).
|
2014-01-06 23:50:25 +01:00
|
|
|
* std: The `Either` type has been removed.
|
2013-12-31 23:35:01 +01:00
|
|
|
* std: `fmt::Default` can be implemented for any type to provide default
|
|
|
|
|
formatting to the `format!` macro, as in `format!("{}", myfoo)`.
|
|
|
|
|
* std: The `rand` API continues to be tweaked.
|
2014-07-05 06:22:59 +02:00
|
|
|
* std: The `rust_begin_unwind` function, useful for inserting breakpoints
|
2014-01-06 23:50:25 +01:00
|
|
|
on failure in gdb, is now named `rust_fail`.
|
|
|
|
|
* std: The `each_key` and `each_value` methods on `HashMap` have been
|
|
|
|
|
replaced by the `keys` and `values` iterators.
|
2013-12-31 23:35:01 +01:00
|
|
|
* std: Functions dealing with type size and alignment have moved from the
|
|
|
|
|
`sys` module to the `mem` module.
|
|
|
|
|
* std: The `path` module was written and API changed.
|
|
|
|
|
* std: `str::from_utf8` has been changed to cast instead of allocate.
|
|
|
|
|
* std: `starts_with` and `ends_with` methods added to vectors via the
|
|
|
|
|
`ImmutableEqVector` trait, which is in the prelude.
|
|
|
|
|
* std: Vectors can be indexed with the `get_opt` method, which returns `None`
|
|
|
|
|
if the index is out of bounds.
|
|
|
|
|
* std: Task failure no longer propagates between tasks, as the model was
|
|
|
|
|
complex, expensive, and incompatible with thread-based tasks.
|
|
|
|
|
* std: The `Any` type can be used for dynamic typing.
|
|
|
|
|
* std: `~Any` can be passed to the `fail!` macro and retrieved via
|
|
|
|
|
`task::try`.
|
|
|
|
|
* std: Methods that produce iterators generally do not have an `_iter`
|
|
|
|
|
suffix now.
|
|
|
|
|
* std: `cell::Cell` and `cell::RefCell` can be used to introduce mutability
|
|
|
|
|
roots (mutable fields, etc.). Use instead of e.g. `@mut`.
|
|
|
|
|
* std: `util::ignore` renamed to `prelude::drop`.
|
|
|
|
|
* std: Slices have `sort` and `sort_by` methods via the `MutableVector`
|
|
|
|
|
trait.
|
|
|
|
|
* std: `vec::raw` has seen a lot of cleanup and API changes.
|
|
|
|
|
* std: The standard library no longer includes any C++ code, and very
|
|
|
|
|
minimal C, eliminating the dependency on libstdc++.
|
|
|
|
|
* std: Runtime scheduling and I/O functionality has been factored out into
|
|
|
|
|
extensible interfaces and is now implemented by two different crates:
|
|
|
|
|
libnative, for native threading and I/O; and libgreen, for green threading
|
|
|
|
|
and I/O. This paves the way for using the standard library in more limited
|
2014-07-05 06:22:59 +02:00
|
|
|
embedded environments.
|
2013-12-31 23:35:01 +01:00
|
|
|
* std: The `comm` module has been rewritten to be much faster, have a
|
|
|
|
|
simpler, more consistent API, and to work for both native and green
|
|
|
|
|
threading.
|
|
|
|
|
* std: All libuv dependencies have been moved into the rustuv crate.
|
|
|
|
|
* native: New implementations of runtime scheduling on top of OS threads.
|
|
|
|
|
* native: New native implementations of TCP, UDP, file I/O, process spawning,
|
|
|
|
|
and other I/O.
|
|
|
|
|
* green: The green thread scheduler and message passing types are almost
|
|
|
|
|
entirely lock-free.
|
|
|
|
|
* extra: The `flatpipes` module had bitrotted and was removed.
|
|
|
|
|
* extra: All crypto functions have been removed and Rust now has a policy of
|
|
|
|
|
not reimplementing crypto in the standard library. In the future crypto
|
|
|
|
|
will be provided by external crates with bindings to established libraries.
|
|
|
|
|
* extra: `c_vec` has been modernized.
|
|
|
|
|
* extra: The `sort` module has been removed. Use the `sort` method on
|
|
|
|
|
mutable slices.

|
|
|
|
* Tooling
|
2013-12-31 23:35:01 +01:00
|
|
|
* The `rust` and `rusti` commands have been removed, due to lack of
|
|
|
|
|
maintenance.
|
|
|
|
|
* `rustdoc` was completely rewritten.
|
|
|
|
|
* `rustdoc` can test code examples in documentation.
|
|
|
|
|
* `rustpkg` can test packages with the argument, 'test'.
|
|
|
|
|
* `rustpkg` supports arbitrary dependencies, including C libraries.
|
|
|
|
|
* `rustc`'s support for generating debug info is improved again.
|
|
|
|
|
* `rustc` has better error reporting for unbalanced delimiters.
|
|
|
|
|
* `rustc`'s JIT support was removed due to bitrot.
|
|
|
|
|
* Executables and static libraries can be built with LTO (-Z lto)
|
|
|
|
|
* `rustc` adds a `--dep-info` flag for communicating dependencies to
|
|
|
|
|
build tools.

|
|
|
============================
|
2013-09-19 03:51:48 +02:00
|
|
|
|
2013-09-25 20:34:08 +02:00
|
|
|
* ~2200 changes, numerous bugfixes
|
2013-09-19 03:51:48 +02:00
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* The `for` loop syntax has changed to work with the `Iterator` trait.
|
|
|
|
|
* At long last, unwinding works on Windows.
|
2013-09-20 01:50:49 +02:00
|
|
|
* Default methods are ready for use.
|
2013-09-19 03:51:48 +02:00
|
|
|
* Many trait inheritance bugs fixed.
|
|
|
|
|
* Owned and borrowed trait objects work more reliably.
|
|
|
|
|
* `copy` is no longer a keyword. It has been replaced by the `Clone` trait.
|
2013-09-18 06:02:11 +02:00
|
|
|
* rustc can omit emission of code for the `debug!` macro if it is passed
|
|
|
|
|
`--cfg ndebug`
|
2013-09-19 03:51:48 +02:00
|
|
|
* mod.rs is now "blessed". When loading `mod foo;`, rustc will now look
|
|
|
|
|
for foo.rs, then foo/mod.rs, and will generate an error when both are
|
|
|
|
|
present.
|
|
|
|
|
* Strings no longer contain trailing nulls. The new `std::c_str` module
|
|
|
|
|
provides new mechanisms for converting to C strings.
|
|
|
|
|
* The type of foreign functions is now `extern "C" fn` instead of `*u8'.
|
|
|
|
|
* The FFI has been overhauled such that foreign functions are called directly,
|
|
|
|
|
instead of through a stack-switching wrapper.
|
|
|
|
|
* Calling a foreign function must be done through a Rust function with the
|
|
|
|
|
`#[fixed_stack_segment]` attribute.
|
|
|
|
|
* The `externfn!` macro can be used to declare both a foreign function and
|
|
|
|
|
a `#[fixed_stack_segment]` wrapper at once.
|
|
|
|
|
* `pub` and `priv` modifiers on `extern` blocks are no longer parsed.
|
|
|
|
|
* `unsafe` is no longer allowed on extern fns - they are all unsafe.
|
|
|
|
|
* `priv` is disallowed everywhere except for struct fields and enum variants.
|
|
|
|
|
* `&T` (besides `&'static T`) is no longer allowed in `@T`.
|
|
|
|
|
* `ref` bindings in irrefutable patterns work correctly now.
|
|
|
|
|
* `char` is now prevented from containing invalid code points.
|
|
|
|
|
* Casting to `bool` is no longer allowed.
|
2013-09-23 23:17:58 +02:00
|
|
|
* `\0` is now accepted as an escape in chars and strings.
|
2013-09-19 03:51:48 +02:00
|
|
|
* `yield` is a reserved keyword.
|
|
|
|
|
* `typeof` is a reserved keyword.
|
|
|
|
|
* Crates may be imported by URL with `extern mod foo = "url";`.
|
|
|
|
|
* Explicit enum discriminants may be given as uints as in `enum E { V = 0u }`
|
|
|
|
|
* Static vectors can be initialized with repeating elements,
|
|
|
|
|
e.g. `static foo: [u8, .. 100]: [0, .. 100];`.
|
|
|
|
|
* Static structs can be initialized with functional record update,
|
|
|
|
|
e.g. `static foo: Foo = Foo { a: 5, .. bar };`.
|
|
|
|
|

|
|
|
|
|
configuration, similarly to `#[cfg(...)]`.
|

|
|
|
prefixes (default: allow).
|
|
|
|

|
|
`std::unstable::simd`.
|
|
|
|
|

|
|
|
|
|

|
|
|
|
* `print!` and `println!` write formatted strings (using the `format!`
|
|
|
|
|
extension) to stdout.
|
|
|
|
|

|
|
|
|
|
extension) to the new Writers in `std::rt::io`.
|
|
|
|
|
* The library section in which a function or static is placed may
|
|
|
|
|
be specified with `#[link_section = "..."]`.
|
|
|
|
|
* The `proto!` syntax extension for defining bounded message protocols
|
|
|
|
|
was removed.
|
2013-09-20 01:50:49 +02:00
|
|
|
* `macro_rules!` is hygienic for `let` declarations.
|
2013-09-19 03:51:48 +02:00
|
|
|
* The `#[export_name]` attribute specifies the name of a symbol.
|
|
|
|
|
* `unreachable!` can be used to indicate unreachable code, and fails
|
|
|
|
|
if executed.
|
|
|

|
|
|
|
* Libraries
|
|
|
|
|
* std: Transitioned to the new runtime, written in Rust.
|
|
|
|
|
* std: Added an experimental I/O library, `rt::io`, based on the new
|
|
|
|
|
runtime.
|
|
|
|
|
* std: A new generic `range` function was added to the prelude, replacing
|
|
|
|
|
`uint::range` and friends.
|
|
|
|
|
* std: `range_rev` no longer exists. Since range is an iterator it can be
|
|
|
|
|
reversed with `range(lo, hi).invert()`.
|
|
|
|
|
* std: The `chain` method on option renamed to `and_then`; `unwrap_or_default`
|
|
|
|
|
renamed to `unwrap_or`.
|
|
|
|
|
* std: The `iterator` module was renamed to `iter`.
|
|
|
|
|
* std: Integral types now support the `checked_add`, `checked_sub`, and
|
|
|
|
|
`checked_mul` operations for detecting overflow.
|
|
|
|
|
* std: Many methods in `str`, `vec`, `option, `result` were renamed for
|
|
|
|
|
consistency.
|
|
|
|
|
* std: Methods are standardizing on conventions for casting methods:
|
|
|
|
|
`to_foo` for copying, `into_foo` for moving, `as_foo` for temporary
|
|
|
|
|
and cheap casts.
|
|
|
|
|
* std: The `CString` type in `c_str` provides new ways to convert to and
|
|
|
|
|
from C strings.
|
|
|
|
|
* std: `DoubleEndedIterator` can yield elements in two directions.
|
|
|
|
|
* std: The `mut_split` method on vectors partitions an `&mut [T]` into
|
|
|
|
|
two splices.
|
|
|
|
|
* std: `str::from_bytes` renamed to `str::from_utf8`.
|
|
|
|
|
* std: `pop_opt` and `shift_opt` methods added to vectors.
|
|
|
|
|
* std: The task-local data interface no longer uses @, and keys are
|
|
|
|
|
no longer function pointers.
|
|
|
|
|
* std: The `swap_unwrap` method of `Option` renamed to `take_unwrap`.
|
|
|
|
|
* std: Added `SharedPort` to `comm`.
|
|
|
|
|
* std: `Eq` has a default method for `ne`; only `eq` is required
|
|
|
|
|
in implementations.
|
2013-09-20 01:50:49 +02:00
|
|
|
* std: `Ord` has default methods for `le`, `gt` and `ge`; only `lt`
|
2013-09-19 03:51:48 +02:00
|
|
|
is required in implementations.
|
|
|
|
|
* std: `is_utf8` performance is improved, impacting many string functions.
|
|
|
|
|
* std: `os::MemoryMap` provides cross-platform mmap.
|
|
|
|
|
* std: `ptr::offset` is now unsafe, but also more optimized. Offsets that
|
|
|
|
|
are not 'in-bounds' are considered undefined.
|
|
|
|
|
* std: Many freestanding functions in `vec` removed in favor of methods.
|
|
|
|
|
* std: Many freestanding functions on scalar types removed in favor of
|
|
|
|
|
methods.
|
|
|
|
|
* std: Many options to task builders were removed since they don't make
|
|
|
|
|
sense in the new scheduler design.
|
|
|
|
|
* std: More containers implement `FromIterator` so can be created by the
|
|
|
|
|
`collect` method.
|
|
|
|
|
* std: More complete atomic types in `unstable::atomics`.
|
|
|
|
|
* std: `comm::PortSet` removed.
|
|
|
|
|
* std: Mutating methods in the `Set` and `Map` traits have been moved into
|
|
|
|
|
the `MutableSet` and `MutableMap` traits. `Container::is_empty`,
|
|
|
|
|
`Map::contains_key`, `MutableMap::insert`, and `MutableMap::remove` have
|
|
|
|
|
default implementations.
|
2013-09-23 23:17:58 +02:00
|
|
|
* std: Various `from_str` functions were removed in favor of a generic
|
|
|
|
|
`from_str` which is available in the prelude.
|
|
|
|
|
* std: `util::unreachable` removed in favor of the `unreachable!` macro.
|
2013-09-19 03:51:48 +02:00

|
|
|
|
* extra: `deque` was renamed to `ringbuf`. `RingBuf` implements `Deque`.
|
|
|
|
|
* extra: `net`, and `timer` were removed. The experimental replacements
|
|
|
|
|
are `std::rt::io::net` and `std::rt::io::timer`.
|
|
|
|
|
* extra: Iterators implemented for `SmallIntMap`.
|
|
|
|
|
* extra: Iterators implemented for `Bitv` and `BitvSet`.
|
|
|
|
|
* extra: `SmallIntSet` removed. Use `BitvSet`.
|
|
|
|
|
* extra: Performance of JSON parsing greatly improved.
|
|
|
|

|
|
|
* Other
|
|
|
|
|
* rustc's debug info generation (`-Z debug-info`) is greatly improved.
|
|
|
|
|
* rustc accepts `--target-cpu` to compile to a specific CPU architecture,
|
|
|
|
|
similarly to gcc's `--march` flag.
|
2013-09-20 20:49:27 +02:00
|
|
|
* rustc's performance compiling small crates is much better.
|

|
|
|
* rustpkg has received many improvements.
|
|
|
|
|
* rustpkg supports git tags as package IDs.
|
|
|
|
|
* rustpkg builds into target-specific directories so it can be used for
|
|
|
|
|
cross-compiling.
|
|
|
|
|
* The number of concurrent test tasks is controlled by the environment
|
|
|
|
|
variable RUST_TEST_TASKS.
|
|
|
|
|
* The test harness can now report metrics for benchmarks.
|
|
|
|
|
* All tools have man pages.
|
|
|
|
|
* Programs compiled with `--test` now support the `-h` and `--help` flags.
|
|

|
* The runtime uses jemalloc for allocations.
|
|
|
|
|
* Segmented stacks are temporarily disabled as part of the transition to
|
|
|
|
|
the new runtime. Stack overflows are possible!
|
2013-09-22 08:25:48 +02:00
|
|
|
* A new documentation backend, rustdoc_ng, is available for use. It is
|
|
|
|
|
still invoked through the normal `rustdoc` command.

|
removed due to bugs.
|
2013-06-16 01:57:37 +02:00

|
|
|
|
|
so they compose better.
|
2013-07-01 00:02:52 +02:00
|
|
|

|
|
|
|
|
The `#[main]` attribute is still valid anywhere.
|
|
|
|
|
* Struct fields may no longer be mutable. Use inherited mutability.
|
2013-07-01 00:02:52 +02:00
|

|
|
|
|
|
`Send`, not.
|
|
|
|
|
* The `#[no_freeze]` attribute makes a type that would otherwise be
|
|

|
2013-03-12 02:27:41 +01:00
|
|
|
|
|
|
|
|
* Syntax changes
|
|
|
|
|
* The self type parameter in traits is now spelled `Self`
|
2013-03-22 19:59:59 +01:00
|
|
|
* The `self` parameter in trait and impl methods must now be explicitly
|
|
|
|
|
named (for example: `fn f(&self) { }`). Implicit self is deprecated.
|
2013-03-26 20:28:04 +01:00
|
|
|
* Static methods no longer require the `static` keyword and instead
|
|
|
|
|
are distinguished by the lack of a `self` parameter
|
2013-03-12 02:27:41 +01:00
|
|
|
* Replaced the `Durable` trait with the `'static` lifetime
|
|
|
|
|
* The old closure type syntax with the trailing sigil has been
|
|
|
|
|
removed in favor of the more consistent leading sigil
|
|
|
|
|
* `super` is a keyword, and may be prefixed to paths
|
|
|
|
|
* Trait bounds are separated with `+` instead of whitespace
|
|
|
|
|
* Traits are implemented with `impl Trait for Type`
|
|
|
|
|
instead of `impl Type: Trait`
|
2013-03-26 20:28:04 +01:00
|
|
|
* Lifetime syntax is now `&'l foo` instead of `&l/foo`
|
2013-03-12 02:27:41 +01:00
|
|
|
* The `export` keyword has finally been removed
|
2013-03-22 19:59:59 +01:00
|
|
|
* The `move` keyword has been removed (see "Semantic changes")
|
2013-03-12 02:27:41 +01:00
|
|
|
* The interior mutability qualifier on vectors, `[mut T]`, has been
|
|
|
|
|
removed. Use `&mut [T]`, etc.
|
|
|
|
|
* `mut` is no longer valid in `~mut T`. Use inherited mutability
|
|
|
|
|
* `fail` is no longer a keyword. Use `fail!()`
|
|
|
|
|
* `assert` is no longer a keyword. Use `assert!()`
|
|
|
|
|
* `log` is no longer a keyword. use `debug!`, etc.
|
|
|
|
|
* 1-tuples may be represented as `(T,)`
|
|
|
|
|
* Struct fields may no longer be `mut`. Use inherited mutability,
|
|
|
|
|
`@mut T`, `core::mut` or `core::cell`
|
|
|
|
|
* `extern mod { ... }` is no longer valid syntax for foreign
|
|
|
|
|
function modules. Use extern blocks: `extern { ... }`
|
2013-03-31 23:37:04 +02:00
|
|
|
* Newtype enums removed. Use tuple-structs.
|
2013-03-12 02:27:41 +01:00
|
|
|
* Trait implementations no longer support visibility modifiers
|
2013-03-22 19:59:59 +01:00
|
|
|
* Pattern matching over vectors improved and expanded
|
2013-03-22 20:41:42 +01:00
|
|
|
* `const` renamed to `static` to correspond to lifetime name,
|
|
|
|
|
and make room for future `static mut` unsafe mutable globals.
|
2013-03-26 20:28:04 +01:00
|
|
|
* Replaced `#[deriving_eq]` with `#[deriving(Eq)]`, etc.
|
2013-03-24 13:57:58 +01:00

|
|
|
|
|
`#[deriving(Clone)]`
|
2013-03-26 20:28:04 +01:00
|
|
|
* Casts to traits must use a pointer sigil, e.g. `@foo as @Bar`
|
|
|
|
|
instead of `foo as Bar`.
|
2013-03-31 23:37:04 +02:00
|
|
|
* Fixed length vector types are now written as `[int, .. 3]`
|
|
|
|
|
instead of `[int * 3]`.
|
|
|
|
|
* Fixed length vector types can express the length as a constant
|
|
|
|
|
expression. (ex: `[int, .. GL_BUFFER_SIZE - 2]`)
|
2013-03-12 02:27:41 +01:00

|
|
|
|
|
|
|
* Semantic changes
|
2013-03-13 21:47:49 +01:00
|
|
|
* Types with owned pointers or custom destructors move by default,
|
|
|
|
|
eliminating the `move` keyword
|

|
|
* All foreign functions are considered unsafe
|
|
|
|

|
|
|
|
|
* The name of the main function can be customized using #[main]
|
|
|
|
|
* The default type of an inferred closure is &fn instead of @fn
|
2013-03-26 20:28:04 +01:00
|
|
|
* `use` statements may no longer be "chained" - they cannot import
|
|
|
|
|
identifiers imported by previous `use` statements
|
|
|
|
|
* `use` statements are crate relative, importing from the "top"
|
|
|
|
|
of the crate by default. Paths may be prefixed with `super::`
|
|
|
|
|
or `self::` to change the search behavior.
|
2013-03-12 02:27:41 +01:00
|
|
|
* Method visibility is inherited from the implementation declaration
|
|
|
|
|

|
|
|
|
