feat: better completions for extern blcoks
This PR refactors `add_keywords` (making it much clearer!) and enhances completion for `extern` blocks.
It is recommended to reviewing the changes in order of the commits:
- The first commit (f3c4dde0a4) doesn’t change any logic but refactors parts of the `add_keywords` function and adds detailed comments.
- The second commit (5dcc1ab649) improves completion for `extern` kw and extern blocks.
Add wrap/unwrap return type in Option
I pretty much just copied over the code and tests for wrapping/unwrapping return types in `Result` and then did a bunch of find and replace changes.
I handled unwrapping statements returning `None` by just replacing `None` with the unit type, but I'm open to suggestions for more intuitive behavior here.
LSP says about Position::character
> If the character value is greater than the line length it defaults back to the line length.
but from_proto::offset() doesn't implement this.
A client might for example request code actions for a whole line by sending
Position::character=99999. I don't think there is ever a reason (besides laziness) why the
client can't specify the line length instead but I guess we should not crash but follow protocol.
Technically it should be a warning, not an error but warning is not shown by default so keep
it at error I guess.

chore: rename `salsa` to `ra_salsa`
Laying some groundwork to start before I import the new Salsa crate. Here's why:
1. As part of the migration, `@darichey,` `@Wilfred,` and I will create new Salsa equivalents of the existing databases/query groups. We'll get them to compile crate-by-crate.
2. Once we wrote all equivalents of all queries, we'd start to refactor usage sites of the vendored Salsa to use the new Salsa databases.
3. Starting porting usage sites of old Salsa to the new Salsa.
4. Remove the vendored `ra_salsa`; declare victory.

fix: Do not consider mutable usage of deref to `*mut T` as deref_mut
Fixes#15799
We are doing some heuristics for deciding whether the given deref is deref or deref_mut here;
5982d9c420/crates/hir-ty/src/infer/mutability.rs (L182-L200)
But this heuristic is erroneous if we are dereferencing to a mut ptr and normally those cases are filtered out here as builtin;
5982d9c420/crates/hir-ty/src/mir/lower/as_place.rs (L165-L177)
Howerver, this works not so well if the given dereferencing is double dereferencings like the case in the #15799.
```rust
struct WrapPtr(*mut u32);
impl core::ops::Deref for WrapPtr {
type Target = *mut u32;
fn deref(&self) -> &Self::Target {
&self.0
}
}
fn main() {
let mut x = 0u32;
let wrap = WrapPtr(&mut x);
unsafe {
**wrap = 6;
}
}
```
Here are two - outer and inner - dereferences here, and the outer dereference is marked as deref_mut because there is an assignment operation.
And this deref_mut marking is propagated into the inner dereferencing.
In the later MIR lowering, the outer dereference is filtered out as it's expr type is `*mut u32`, but the expr type in the inner dereference is an ADT, so this false-mutablility is not filtered out.
This PR cuts propagation of this false mutablilty chain if the expr type is mut ptr.
Since this happens before the resolve_all, it may have some limitations when the expr type is determined as mut ptr at the very end of inferencing, but I couldn't find simple fix for it 🤔
internal: Don't resolve extern crates in import fix point resolution
The fix point loop won't progress them given the potential extern crate candidates are set up at build time.
fix: Join rustfmt overrideCommand with project root
When providing a custom rustfmt command, join it with the project root instead of the workspace root. This fixes rust-analyzer getting the wrong invocation path in projects containing subprojects.
This makes the behaviour consistent with how a custom path provided in rust-analyzer.procMacro.server behaves already.
Resolves issue #18222
feat: Highlight exit points of async blocks
Async blocks act similar to async functions in that the await keywords are related, but also act like functions where the exit points are related.
Fixes#18147
fix: include description in label details when detail field is marked for …
Fixes https://github.com/rust-lang/rust-analyzer/issues/18231.
When omitting the autocomplete detail field, the autocomplete label details can still be returned. Currently the label details are missing the description field if the detail field is included in resolveSupport since it is being overwritten as None and opted to be sent with `completionItem/resolve`.
Example completion capabilities.
```
completion = {
completionItem = {
commitCharactersSupport = true,
deprecatedSupport = true,
documentationFormat = { "markdown", "plaintext" },
insertReplaceSupport = true,
insertTextModeSupport = {
valueSet = { 1, 2 }
},
labelDetailsSupport = true,
preselectSupport = true,
resolveSupport = {
properties = { "documentation", "detail", "additionalTextEdits", "sortText", "filterText", "insertText", "textEdit", "insertTextFormat", "insertTextMode" }
},
snippetSupport = true,
tagSupport = {
valueSet = { 1 }
}
}
```
lsp: fix completion_item something_to_resolve not being a latch to true
while looking at #18245 i noticed that `something_to_resolve` could technically flap between true -> false if some subsequent fields that were requested to be resolved were empty.
this fixes that by using `|=` instead of `=` when assigning to `something_to_resolve` which will prevent it from going back to false once set.
although some cases it's simply assigning to `true` i opted to continue to use `|=` there for uniformity sake. but happy to change those back to `=`'s.
