internal: Only compare relevant parts in `ide::{runnables,inlay_hints}` tests
This PR limits the data being compared. Therefore the tests should be more readable, as well as being more robust to changes to the data structure.
Part of https://github.com/rust-lang/rust-analyzer/issues/14268.
internal: Move query limits to the caller
Prior we calculated up to `limit` entries from a query, then filtered from that leaving us with less entries than the limit in some cases (which might give odd completion behavior due to items disappearing). This changes it so we filter before checking the limit.
feat: resolve inherent and implemented associated items in docs
This partially fixes#9694.
Supported:
- Trait methods and constants.
* Due to resolution differences pointed out during the review of the PR, trait associated types are _not_ supported.
- Inherent methods, constants and associated types.
* Inherent associated types are a [nightly feature](https://github.com/rust-lang/rust/issues/8995), and are supported with no additional work in this PR.

You can see that the items are resolved (excl. trait associated types) since they are semantically highlighted in the doc comment.
SymbolInformation::kind is finer-grained than the SCIP symbol suffix.
This also fixes a bug where all type aliases where treated like type
parameters.
```
trait SomeTrait {
type AssociatedType; // ← this is SomeTrait#[AssociatedType]
}
type MyTypeAlias = u8; // ← this used to be [MyTypeAlias]
// and now is MyTypeAlias#
```
To build the SymbolInformation::signature_documentation we need access
to the “label” when building the TokenStaticData, preferably without
any markdown markup.
Therefore this refactors ide::hover::render::definition and its helper
functions to give easier access to the label alone.
For local variables, this gets the moniker from the enclosing
definition and stores it into the TokenStaticData.
Then it builds the scip symbol for that moniker when building the
SymbolInformation.
Complete exported macros in `#[macro_use($0)]`
Closes https://github.com/rust-lang/rust-analyzer/issues/15657.
Originally added a test case for incomplete input:
```rust
#[test]
fn completes_incomplete_syntax() {
check(
r#"
//- /dep.rs crate:dep
#[macro_export]
macro_rules! foo {
() => {};
}
//- /main.rs crate:main deps:dep
#[macro_use($0
extern crate dep;
"#,
expect![[r#"
ma foo
"#]],
)
}
```
but couldn't make it pass and removed it 😅 Our current recovering logic doesn't work for token trees and for this code:
```rust
#[macro_use(
extern crate lazy_static;
fn main() {}
```
we ended up with this syntax tree:
```
SOURCE_FILE@0..53
ATTR@0..52
POUND@0..1 "#"
L_BRACK@1..2 "["
META@2..52
PATH@2..11
PATH_SEGMENT@2..11
NAME_REF@2..11
IDENT@2..11 "macro_use"
TOKEN_TREE@11..52
L_PAREN@11..12 "("
WHITESPACE@12..13 "\n"
EXTERN_KW@13..19 "extern"
WHITESPACE@19..20 " "
CRATE_KW@20..25 "crate"
WHITESPACE@25..26 " "
IDENT@26..37 "lazy_static"
SEMICOLON@37..38 ";"
WHITESPACE@38..40 "\n\n"
FN_KW@40..42 "fn"
WHITESPACE@42..43 " "
IDENT@43..47 "main"
TOKEN_TREE@47..49
L_PAREN@47..48 "("
R_PAREN@48..49 ")"
WHITESPACE@49..50 " "
TOKEN_TREE@50..52
L_CURLY@50..51 "{"
R_CURLY@51..52 "}"
WHITESPACE@52..53 "\n"
```
Maybe we can try to parse the token tree in `crates/ide-completion/src/context/analysis.rs` but I'm not sure what's the best way forward.
fix: Update metavariable expression implementation
Fixes https://github.com/rust-lang/rust-analyzer/issues/16154
This duplicates behavior of that before and after PR https://github.com/rust-lang/rust/pull/117050 based on the toolchain version. There are some 1.76 nightlies that are still broken (any before that PR basically) but fetching and storing the commit makes little sense to me (opposed to the toolchain version).
minor: Use reserve when removing markdown from text
After markdown syntax removal the length of the text is roughly the same so we can reserve memory beforehand
