4882: _match.rs: improve comment formatting r=matklad a=jonas-schievink
This results in much nicer rustdoc output
Co-authored-by: Jonas Schievink <jonasschievink@gmail.com>
It's a good idea to distinguish between absolute and relative paths at
the type level, to avoid accidental dependency on the cwd, which
really shouldn't matter for rust-analyzer service
4700: Add top level keywords completion r=matklad a=mcrakhman
This fixes the following issue: https://github.com/rust-analyzer/rust-analyzer/issues/4566.
Also added simple logic which filters the keywords which can be used with unsafe on the top level.

4857: Fix invalid shorthand initialization diagnostic for tuple structs r=jonas-schievink a=OptimalStrategy
Initializing tuple structs explicitly, like in the example below, produces a "Shorthand struct initialization" diagnostic that leads to a compilation error when applied:
```rust
struct S(usize);
fn main() {
let s = S { 0: 0 }; // OK, but triggers the diagnostic
// let s = S { 0 }; // Compilation error
}
```
This PR adds a check that the field name is not a literal.

4833: Separating parsing of `for` in predicates and types r=matklad a=matthewjasper
We now correctly accept `for<'a> (&'a F): Fn(&'a str)` in a where clause and correctly reject `for<'a> &'a u32` as a type.

4849: Make known paths use `core` instead of `std` r=matklad a=jonas-schievink
I'm not sure if this causes problems today, but it seems like it easily could, if rust-analyzer processes the libstd sources for the right `--target` and that target is a `#![no_std]`-only target.

4819: Add an FST index to `ImportMap` and use it to speed up auto import r=matklad a=jonas-schievink
For the importing crate, we still use the symbol index, but I've modified it to only look at files that comprise that crate (instead of the whole workspace).
Oh, and since now the symbol query limit is respected correctly, it's possible that some results from the local crate now disappear if there are many matches.
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/4763

4576: Add implementation of extract struct from enum variant r=matklad a=mcrakhman
Hi guys! I implemented the extraction functionality including modifying multiple files. The only thing I didn't change the cursor position. I've done it with a previous API, but now snippets have been introduced and I need to figure out how to do it.
Please bear in mind that I am a newcomer in the rust-analyzer (and also Rust) world, so I tried to implement the feature to the best of my knowledge, but the API is very new to me, so I am very welcome to introducing changes etc.

4784: Change management of test cfg to better support json projects r=Nashenas88 a=Nashenas88
This helps support json projects where they can decide whether to add the `test` cfg or not. One alternative is to add support for marking json project crates as a sysroot crate, and adding logic to remove the `test` cfg in those cases. In my opinion, that option gives less flexibility to json projects and leads to more functionality that needs to be maintained.
Fixes#4508

4683: Implement syntax highlighting for doctests r=ltentrup a=ltentrup
The implementation is more complicated than the previous injection logic as the doctest comments consist of multiple ranges. The implementation extracts the doctests together with an offset-mapping, applies the syntax highlighting, and updates the text ranges.

4781: Remove redundancy in syntax highlighting tests r=matklad a=ltentrup
Follow up from #4683. Improves syntax highlighting testing by introducing a function that contains the boilerplate comparison code. Keeps the `ra_fixture` argument in the first position, thus, the editor syntax highlighting injection still works.

4770: Clean up handling of int/float literal types r=matklad a=flodiebold
'Unknown' int/float types actually never exist as such, they get replaced by type variables immediately. So the whole `Uncertain<IntTy>` thing was unnecessary and just led to a bunch of match branches that were never hit.

4689: Implement return position impl trait / opaque type support r=matklad a=flodiebold
This is working, but I'm not that happy with how the lowering works. We might need an additional representation between `TypeRef` and `Ty` where names are resolved and `impl Trait` bounds are separated out, but things like inference variables don't exist and `impl Trait` is always represented the same way.
Also note that this doesn't implement correct handling of RPIT *inside* the function (which involves turning the `impl Trait`s into variables and creating obligations for them). That intermediate representation might help there as well.

4748: Add an `ImportMap` and use it to resolve item paths in `find_path` r=matklad a=jonas-schievink
Removes the "go faster" queries I added in https://github.com/rust-analyzer/rust-analyzer/pull/4501 and https://github.com/rust-analyzer/rust-analyzer/pull/4506. I've checked this PR on the rustc code base and the assists are still fast.
This should fix https://github.com/rust-analyzer/rust-analyzer/issues/4515.
Note that this does introduce a change in behavior: We now always refer to items defined in external crates using paths through the external crate. Previously we could also use a local path (if for example the extern crate was reexported locally), as seen in the changed test. If that is undesired I can fix that, but the test didn't say why the previous behavior would be preferable.
