370: Self params & type r=matklad a=flodiebold
This implements type inference for `self`, so field completion for methods taking `self` works now.
- rename `IMPL_ITEM` to `IMPL_BLOCK` -- rustc calls the methods etc. inside an impl `ImplItem`s, and the impl itself doesn't define an item, so I thought this name was clearer.
- add HIR for impl blocks -- we collect all impls in a crate at once, so we can go from methods to containing impls, and since we will later also need to find all impls for a certain type (which may be anywhere in the crate, I think?). We could be more lazy here, but I don't know if it's worth the complexity.
- resolve `self` and `Self` during type inference
- refactor a bit in ty.rs as well

Since we need to be able to go from def to containing impl block, as well as the
other direction, and to find all impls for a certain type, a design similar to
the one for modules, where we collect all impls for the whole crate and keep
them in an arena, seemed fitting. The ImplBlock type, which provides the public
interface, then consists only of an Arc to the arena containing all impls, and
the index into it.

396: Fix the `panic` found whilst fuzzing r=matklad,me a=DJMcNab
This occurred when a non-ascii character was used in an ascii escape, for example in the motivating example: `if'\xɿ`, which can be further simplified to `'\xɿ`.

Attempting to format a document when rustfmt isn't installed will result

This will really become necessary when we implement generics, but even now, it
allows us to reason 'backwards' to infer types of expressions that we didn't
understand for some reason.
We use ena, the union-find implementation extracted from rustc, to keep track of
type variables.
350: Super simple macro support r=matklad a=matklad
Super simple support for macros, mostly for figuring out how to fit them into the current architecture. Expansion is hard-coded and string based (mid-term, we should try to copy-paste macro-by-example expander from rustc).
Ideally, we should handle
* highlighting inside the macro (done)
* extend selection inside the macro
* completion inside the macro
* indexing structs, produced by the macro

332: Struct types r=matklad a=flodiebold
Infer types for struct fields, and add basic field completions. There's also some code for enums, but I focused on getting structs working.
There's still ways to go before this becomes useful: There's no autoderef (or even reference types) and no inference for `self`, for example.

We need to be able to get the receiver even if there is no field name yet, and
currently "a." wouldn't get parsed as a field name at all. This seems to help.

327: Beginnings of type inference r=flodiebold a=flodiebold
I was a bit bored, so I thought I'd try to start implementing the type system and see how far I come 😉 This is obviously still extremely WIP, only very basic stuff working, but I thought I'd post this now to get some feedback as to whether this approach makes sense at all.
There's no user-visible effect yet, but the type inference has tests similar to the ones for the parser. My next step will probably be to implement struct types, after which this could probably be used to complete fields.
I realize this may all get thrown away when/if the compiler query system gets usable, but I feel like there are lots of IDE features that could be implemented with somewhat working type inference in the meantime 😄

306: Finish weird exprs r=DJMcNab a=DJMcNab
Fix#290.
Note that I'm not certain my use of `p.nth(1) == Ident` is entirely consistent with `libsyntax` - in the original, [`is_union_item`](9622f9dc47/src/libsyntax/parse/parser.rs (L4593-L4596)) uses `t.is_ident() && !t.is_reserved_ident()`, whereas we effectively only do `is_ident`. However, I cannot find the definition of `is_reserved_ident` (even searching the rust repository only gives uses, no definitions), so this will have to do unless someone else can find it :|.

273: Add a test to ensure that we can parse each file r=matklad a=DJMcNab
Note that this has a non-spurious failure in ra_analysis/src/mock_analysis.

Co-authored-by: DJMcNab <36049421+djmcnab@users.noreply.github.com>
This fixes a common problem when running under VS Code, the user
doesn't have permissions to create a `log` directory in the CWD.
The old behavior can be re-enabled by setting RA_INTERNAL_MODE=1
The cast expression expected any type via types::type_() function,
but the language spec does only allow TypeNoBounds (types without direct extra bounds
via `+`).
**Example:**
```rust
fn test() {
6i8 as i32 + 5;
}
```
This fails, because the types::type_() function which should parse the type after the
as keyword is greedy, and takes all plus sign after path types as extra.
My proposed fix is to replace the not implemented `type_no_plus()` just calls (`type_()`)
function, which is used at several places. The replacement is `type_with_bounds_cond(p: &mut Parser, allow_bounds: bool)`, which passes the condition to relevant sub-parsers.
This function is then called by `type_()` and the new public `type_no_bounds()`.
271: Implement format hook r=matklad a=DJMcNab
Tentatively: fixes#155.
However, this does add all changes in staged files, which might not be desirable. However, I think we can't solve that without explicit support in rustfmt for it, so it should be fine.
