Partially fixes#15656 . When a crate graph is extended which is the case when new workspaces are added to the project
the rules for deduplication were too strict. One problem that arises from this is that in certain conditions
when we see the same crate having different `CrateOrigin`s the first form would be maintained. This approach however
results in some unwanted results such as making renaming forbidden as this has been recently only made available for
local crates. The given example in #15656 can still not be resolved with this PR as that involves taking inconsistencies
between dependencies into consideration. This will be addressed in a future PR.
code: expose workspaces to other extensions; remove `addProject` command
This (mostly red) PR does three things:
- Exposes two methods to companion extensions (`setWorkspaces` and `notifyRustAnalyzer`).
- `setWorkspaces` is needed to update `linkedProjects` _without_ writing workspace/global configuration.
- `notifyRustAnalyzer` to get the server to pull the new configuration.
- Makes `Ctx` implement `RustAnalyzerExtensionApi` to prevent accidental regressions.
- Remove `rust-analyzer.addProject`, as that will live in a buck2 companion extension. No need for that to be in rust-analyzer!
I can see the utility of combining `notifyRustAnalyzer` and `setWorkspaces` into a single method (`updateWorkspacesAndNotify()`?), but I don't feel strongly about this. My feeling is that this API could be easily changed in the future.
fix: Diagnose everything in nested items, not just def diagnostics
Turns out we only calculated def diagnostics for these before (was wondering why I wasn't getting any type mismatches)
internal: Migrate assists to the structured snippet API, part 4
Continuing from #15260
Migrates the following assists:
- `add_turbo_fish`
- `add_type_ascription`
- `destructure_tuple_binding`
- `destructure_tuple_binding_in_subpattern`
I did this a while ago, but forgot to make a PR for the changes until now. 😅
