This change makes the compiler no longer infer whether types (structures
and enumerations) implement the `Copy` trait (and thus are implicitly
copyable). Rather, you must implement `Copy` yourself via `impl Copy for
MyType {}`.
A new warning has been added, `missing_copy_implementations`, to warn
you if a non-generic public type has been added that could have
implemented `Copy` but didn't.
For convenience, you may *temporarily* opt out of this behavior by using
`#![feature(opt_out_copy)]`. Note though that this feature gate will never be
accepted and will be removed by the time that 1.0 is released, so you should
transition your code away from using it.
This breaks code like:
#[deriving(Show)]
struct Point2D {
x: int,
y: int,
}
fn main() {
let mypoint = Point2D {
x: 1,
y: 1,
};
let otherpoint = mypoint;
println!("{}{}", mypoint, otherpoint);
}
Change this code to:
#[deriving(Show)]
struct Point2D {
x: int,
y: int,
}
impl Copy for Point2D {}
fn main() {
let mypoint = Point2D {
x: 1,
y: 1,
};
let otherpoint = mypoint;
println!("{}{}", mypoint, otherpoint);
}
This is the backwards-incompatible part of #13231.
Part of RFC #3.

Rust documentations
Dependencies
Pandoc, a universal document converter, is required to generate docs as HTML from Rust's source code.
po4a is required for generating translated docs from the master (English) docs.
GNU gettext is required for managing the translation data.
Building
To generate all the docs, just run make docs from the root of the repository.
This will convert the distributed Markdown docs to HTML and generate HTML doc
for the 'std' and 'extra' libraries.
To generate HTML documentation from one source file/crate, do something like:
rustdoc --output html-doc/ --output-format html ../src/libstd/path.rs
(This, of course, requires a working build of the rustdoc tool.)
Additional notes
To generate an HTML version of a doc from Markdown manually, you can do something like:
pandoc --from=markdown --to=html5 --number-sections -o reference.html reference.md
(reference.md being the Rust Reference Manual.)
The syntax for pandoc flavored markdown can be found at:
A nice quick reference (for non-pandoc markdown) is at:
Notes for translators
Notice: The procedure described below is a work in progress. We are working on translation system but the procedure contains some manual operations for now.
To start the translation for a new language, see po4a.conf at first.
To generate .pot and .po files, do something like:
po4a --copyright-holder="The Rust Project Developers" \
--package-name="Rust" \
--package-version="0.13.0" \
-M UTF-8 -L UTF-8 \
src/doc/po4a.conf
(the version number must be changed if it is not 0.13.0 now.)
Now you can translate documents with .po files, commonly used with gettext. If
you are not familiar with gettext-based translation, please read the online
manual linked from http://www.gnu.org/software/gettext/ . We use UTF-8 as the
file encoding of .po files.
When you want to make a commit, do the command below before staging your change:
for f in src/doc/po/**/*.po; do
msgattrib --translated $f -o $f.strip
if [ -e $f.strip ]; then
mv $f.strip $f
else
rm $f
fi
done
This removes untranslated entries from .po files to save disk space.
