6251: Semantic Highlight: Add Callable modifier for variables r=matklad a=GrayJack
This PR added the `HighlightModifier::Callable` variant and assigned it to variables and parameters that are fn pointers, closures and implements FnOnce trait.
This allows to colorize these variables/parameters when used in call expression.
6310: Rewrite algo::diff to support insertion and deletion r=matklad a=Veykril
This in turn also makes `algo::diff` generate finer diffs(maybe even minimal diffs?) as insertions and deletions aren't always represented as as replacements of parent nodes now.
Required for #6287 to go on.

Unfortunately I ran into https://github.com/rust-analyzer/rust-analyzer/issues/4058 while testing this on https://github.com/nrf-rs/nrf-hal/, so I didn't see much of it in action yet, but it does seem to work.

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
5917: Add a command to open docs for the symbol under the cursor r=matklad a=zacps
#### Todo
- [ ] Decide if there should be a default keybind or context menu entry
- [x] Figure out how to get the documentation path for methods and other non-top-level defs
- [x] Design the protocol extension. In future we'll probably want parameters for local/remote documentation URLs, so that should maybe be done in this PR?
- [x] Code organisation
- [x] Tests

Return an error with a meaningful message for requests to
`textDocument/rename` if the operation cannot be performed.
Pass errors raised by rename handling code to the LSP runtime.
As a consequence, the VS Code client shows and logs the request
as if a server-side programming error occured.
Resolves https://github.com/rust-analyzer/rust-analyzer/issues/3981
Percentage is a UI concern, the physical fact here is fraction. It's
sad that percentage bleeds into the protocol level, we even duplicated
this bad API ourselves!
6124: Better normalized crate name usage r=jonas-schievink a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5343
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5932
Uses normalized name for code snippets (to be able to test the fix), hover messages and documentation rewrite links (are there any tests for those?).
Also renamed the field to better resemble the semantics.

This removes all markdown when the client does not support the markdown MarkupKind
Otherwise the output on the editor will have some markdown boilerplate, making it less readable
This seems like a better factoring logically; ideally, clients shouldn't touch
`set_` methods of the database directly. Additionally, I think this
should remove the unfortunate duplication in fixture code.
6018: Correct project_root path for ProjectJson. r=jonas-schievink a=woody77
It was already the folder containing the rust-project.json file, not the file itself. This also removes the Option-ness of it, since it's now an infallible operation to set the member value.

6017: Don't return any TextEdit if formatting is unchanged r=jonas-schievink a=cuviper
I found that `textDocument/formatting` was always returning a full
`TextEdit` replacement, even when there are no changes, which caused Vim
(w/ vim-lsp) to always indicate a modified buffer after formatting. We
can easily compare whether there were changes and return `null` if not,
so the client knows there's nothing to do.

5643: Add new consuming modifier, apply consuming and mutable to methods r=matklad a=Nashenas88
This adds a new `consuming` semantic modifier for syntax highlighters.
This also emits `mutable` and `consuming` in two cases:
- When a method takes `&mut self`, then it now has `function.mutable` emitted.
- When a method takes `self`, and the type of `Self` is not `Copy`, then `function.consuming` is emitted.

5682: Add an option to disable diagnostics r=matklad a=popzxc
As far as I know, currently it's not possible to disable a selected type of diagnostics provided by `rust-analyzer`.
This causes an inconvenient situation with a false-positive warnings: you either have to disable all the diagnostics, or you have to ignore these warnings.
There are some open issues related to this problem, e.g.: https://github.com/rust-analyzer/rust-analyzer/issues/5412, https://github.com/rust-analyzer/rust-analyzer/issues/5502
This PR attempts to make it possible to selectively disable some diagnostics on per-project basis.

The idea here is that, on CI, we only want to cache crates.io
dependencies, and not local crates. This keeps the size of the cache
low, and also improves performance, as network and moving files on
disk (on Windows) can be slow.

5693: Fix no inlay hints / unresolved tokens until manual edit to refresh r=jonas-schievink a=Veetaha
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/5349
Now we return ContentModified during the workspace loading. This signifies the language
client to retry the operation (i.e. the client will
continue polling the server while it returns ContentModified).
I believe that there might be cases of overly big projects where the backoff
logic we have setup in `sendRequestWithRetry` (which we use for inlay hints)
might bail too early (currently the largest retry standby time is 10 seconds).
However, I've tried on one of my project with 500+ dependencies and it is still enough.
Here are the examples before/after the change (the gifs are quite lengthy because they show testing rather large cargo workspace).
<details>
<summary>Before</summary>
Here you can see that the client receives empty array of inlay hints and does nothing more.
Same applies to semantic tokens. The client receives unresolved tokens and does nothing more.
The user needs to do a manual edit to refresh the editor.
</details>
<details>
<summary>After</summary>
Here the server returns ContentModified, so the client periodically retries the requests and eventually receives the wellformed response.

Closes#5217
The implementation is quite similar to #4821. Maybe we should somehow deal with duplicated code.
Also, both of these requests introduce some unclear behavior. I'm not sure how to process this, therefore asking for advice. Examples are below.

5526: Handle semantic token deltas r=kjeremy a=kjeremy
This basically takes the naive approach where we always compute the tokens but save space sending over the wire which apparently solves some GC problems with vscode.
This is waiting for https://github.com/gluon-lang/lsp-types/pull/174 to be merged. I am also unsure of the best way to stash the tokens into `DocumentData` in a safe manner.

`current_dir` and relative paths to executables works differently on
unix and windows (unix behavior does not make sense), see:
17e30e83a1/src/lib.rs (L295-L324)
The original motivation to set cwd was to make rustfmt read the
correct rustfmt.toml, but that was future proofing, rather than a bug
fix.
So, let's just remove this and see if breaks or fixes more use-cases.
If support for per-file config is needed, we could use `--config-path`
flag.

The methods `edits_for_file` and `find_matches_in_file` are replaced with just `edits` and `matches`. This simplifies the API a bit, but more importantly it makes it possible in a subsequent commit for SSR to decide to not search all files.

5467: Allow null or empty values for configuration r=matklad a=kjeremy
Allow the client to respond to `workspace/configuration` with `null` values. This is allowed per the spec if the client doesn't know about the configuration we've requested.
This also protects against `null` or `{}` during initialize. I'm not sure if we want to interpret `{}` as "don't change anything" but I think that's a reasonable approach to take.
This should help with LSP clients working out of the box.
