The completion of cfg will look at the enabled cfg keys when
performing completion.
It will also look crate features when completing a feature cfg
option. A fixed list of known values for some cfg options are
provided.
For unknown keys it will look at the enabled values for that cfg key,
which means that completion will only show enabled options for those.
8866: Update salsa r=matklad a=jonas-schievink
This updates salsa to include https://github.com/salsa-rs/salsa/pull/265, and removes all cancellation-related code from rust-analyzer
Co-authored-by: Jonas Schievink <jonasschievink@gmail.com>
By including the crate itself, we make the resulting set closed with
respect to `transitve_reveres_dependencies` operation, as it becomes a
proper transitive closure. This just feels more proper and mathy.
And, indeed, this actually allows us to simplify call sites somewhat.
These were the warnings previously:
```

This does *not* fix the following warning, because it is actually rust
code and rustdoc is being over eager:
```
warning: Rust code block is empty
--> crates/parser/src/grammar.rs:16:5
|
16 | //! ```
| _____^
17 | | //! // test function_with_zero_parameters
18 | | //! // fn foo() {}
19 | | //! ```
| |_______^
|
help: mark blocks that do not contain Rust code as text
|
16 | //! ```text
| ^^^^^^^
```
https://github.com/rust-lang/rust/pull/79816 should make this
configurable so the warning can be `allow`ed.
