feat: Add incorrect case diagnostics for traits and their associated items
Updates incorrect case diagnostic to:
- Check traits and their associated items
- Ignore trait implementations except for patterns in associated function bodies
Also cleans up `hir-ty::diagnostics::decl_check` a bit (mostly to make it a bit more DRY and easier to maintain)
Also fixes: #8675 and fixes: #8225
internal: even more `tracing`
As part of profiling completions, I added some additional spans and moved `TyBuilder::subst_for_def` closer to its usage site (the latter had a small impact on completion performance. Thanks for the tip, Lukas!)
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.
fix: Don't emit "missing items" diagnostic for negative impls
Negative impls can't have items, so there is no reason for this diagnostic.
LMK if I should add a test somewhere. Also LMK if that's not how we usually check multiple things in an if in r-a.
