Abstract more over ItemTreeLoc-like structs
Allows reducing some code duplication by using functions generic over said structs. The diff isn't negative due to me adding some additional impls for completeness.
This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.
This commit changes how the expected type is calculated when working
with Fn pointers, making the parenthesis stop vanishing when completing
the function name.
I've been bugged by the behaviour on parenthesis completion for a long
while now. R-a assumes that the `LetStmt` type is the same as the
function type I've just written. Worse is that all parenthesis vanish,
even from functions that have completely different signatures. It will
now verify if the signature is the same.
While working on this, I noticed that record fields behave the same, so
I also made it prioritize the field type instead of the current
expression when possible, but I'm unsure if this is OK, so input is
appreciated.
ImplTraits as return types will still behave weirdly because lowering is
disallowed at the time it resolves the function types.
doc(alias)-based completion round 2
Follow-up on #14433
We can now complete fields, functions and some use/mods.
Flyimports don't behave, I don't really have the time to understand the structure there either.
While reading the flyimport code, I removed one method only used there, the closure-tree was a bit confusing, I can revert that if you want.
feat: show only missing variant suggestion for enums in patterns completion and bump them in list too
Fixes#12438
### Points to help in review:
- This PR can be reviewed commit wise, first commit is about bumping enum variant completions up in the list of completions and second commit is about only showing enum variants which are not complete
- I am calculating missing variants in analysis.rs by firstly locating the enum and then comparing each of it's variant's name and checking if arm string already contains that name, this is kinda hacky but I didn't want to implement complete missing_arms assist here as that would have been too bulky to run on each completion cycle ( if we can improve this somehow would appreciate some inputs on it )

rust-analyzer used the token at the cursor after macro expansion
to decide whether to replace the token at the cursor before macro
expansion. In most cases these two are the same but in some cases these
can mismatch which can lead to incorrect replacements.
For example if an ident/expr macro argument is missing rust-analyzer
generates a "missing" identifier as a placeholder, there is only a
brace at the cursor. Therefore, rust-analyzer will incorrectly replace
the macro brace with the completion in that case leading to #14246.
Using the expanded token type was intentional. However, this doesn't
seem to ever be desirable (this is supported by the fact that there
were no tests that relied on this behavior) since the type of edit to
perform should always be determined by the token it's actually applied
to.
fix a bunch of clippy lints
fixes a bunch of clippy lints for fun and profit
i'm aware of this repo's position on clippy. The changes are split into separate commits so they can be reviewed separately
This makes code more readale and concise,
moving all format arguments like `format!("{}", foo)`
into the more compact `format!("{foo}")` form.
The change was automatically created with, so there are far less change
of an accidental typo.
```
cargo clippy --fix -- -A clippy::all -W clippy::uninlined_format_args
```
I am not certain if this will improve performance,
but it seems having a .clone() without any need should be removed.
This was done with clippy, and manually reviewed:
```
cargo clippy --fix -- -A clippy::all -D clippy::redundant_clone
```
