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.
Handle trait alias definitions
Part of #2773
This PR adds a bunch of structs and enum variants for trait aliases. Trait aliases should be handled as an independent item because they are semantically distinct from traits.
I basically started by adding `TraitAlias{Id, Loc}` to `hir_def::item_tree` and iterated adding necessary stuffs until compiler stopped complaining what's missing. Let me know if there's still anything I need to add.
I'm opening up this PR for early review and stuff. I'm planning to add tests for IDE functionalities in this PR, but not type-related support, for which I put FIXME notes.
Handle case when BlockExpr is child of IfExpr, WhileExpr, LoopExpr,
ForExpr.
An additional { } will be added when:
- It is not a BlockExpr
- It is a BlockExpr and a child of IfExpr, WhileExpr, LoopExpr, ForExpr.
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
```
fix: breaking snippets on typed incomplete suggestions
Possible fix for #7929
Fix the case where if a user types `&&42.o`, snippet completion was still applying &&Ok(42). Note this was fixed previously on `&&42.` but this still remained a problem for this case
Previous relevant PR: #13517
### Points to help in review:
- The main problem why everything broke on adding an extra `o` was, earlier `dot_receiver` was `42.` which was a `LITERAL` but now `42.o` becomes a `FIELD_EXPR`
- Till now `include_references` was just checking for parent of `LITERAL` and if it was a `REF_EXPR`, but now we consider `FIELD_EXPR` and traverse all of them, finally to reach `REF_EXPR`. If `REF_EXPR` is not found we just return the original `initial_element`
- We are constructing a new node during `include_references` because if we rely on `dot_receiver` solely we would get `&&42.o` to be replaced with, but we want `&&42` to be replaced with

Hope everything I wrote makes sense 😅
Also interestingly previous PR's number was `13517` and this PR's number is `13715`, nicee
