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.

Enable hover and autocomplete docs on macro generated items. This de-sugars doc comments into `doc` attributes in some cases, but not all. Comments and `doc` attributes are then merged together.
This PR is essentially a partial implementation of what's being suggested #3182, but it's not all the way there yet. ~I still need to add unit tests~, but I wanted to first get feedback on whether or not this was an acceptable path forward.

Removes the duplicated `expand_doc_attrs` and `merge_doc_comments_and_attrs`
functions from `ra_ide` and exposes the same functionality via
`ra_hir::Documentation::from_ast`.
Eventually, we should support "just open random rust file" use case,
we don't really do this now, so let's avoid spending time on it until
we fix it properly.
4721: Hide squiggly for unused and unnecessary diagnostics r=matklad a=GabbeV
Fixes#4229
When working with JavaScript or TypeScript in VSCode unused valiables are faded but don't have a squiggle. This PR makes rust-analyzer work similarly by setting the severity to hint when applying the unnecessary tag.
VSCode usually shows a squiggle for error, warning and information and shows three dots for hint. When the unnecessary tag is present the squiggles will still show up but the three dots will not.
This is my first contribution to open source. Please tell me if i need to do anything more to get this PR considered.
