Creating rust dependencies tree explorer
Hello!
I tried to implement a tree view that shows the dependencies of a project.
It allows to see all dependencies to the project and it uses `cargo tree` for it. Also it allows to click and open the files, the viewtree tries its best to follow the openned file in the editor.
Here is an example:
Any feedback is welcome since i have basically no professional experience with TS.
Don't merge trait_impls_in_deps results
Closes https://github.com/rust-lang/rust-analyzer/issues/9167
We effectively keep a lot of copies of `TraitImpl` results in memory by merging them into the result of this query. This wastes a lot of memory unnecessarily. The change here brings memory usage of self down by 50mb (at a slight cost of trait solving unfortunately, though I'm hopeful it was just noice)
Refactor symbol index
Closes https://github.com/rust-lang/rust-analyzer/issues/14677
instead of eagerly fetching the source data in symbol index we do it lazily now, this shouldn't make it much more expensive as we had to parse the source most of the time anyways even after fetching.
fix: ide: exclude sized in go-to actions in hover
fixes#13163
i opted to just simply omit `Sized` entirely from go-to actions, as opposed to including it if even someone writes an explicit `T: Sized`, as i think a go-to on Sized is of dubious value practically.
feat: Highlight closure captures when cursor is on pipe or move keyword
This runs into the same issue on vscode as exit points for `->`, where highlights are only triggered on identifiers, https://github.com/rust-lang/rust-analyzer/issues/9395
Though putting the cursor on `move` should at least work.
chore: rust-analyzer: refactor notification handlers
Fixes the FIXME in `on_notification`.
```rust
// FIXME: Move these implementations out into a module similar to on_request
```
No code has changed, this just moves stuff around.
