|\ | | | | | | | | | | | | | | | | | | 6852: Ignore lifetime params in substitutions r=matklad a=Veykril [`hir_ty::utils::Generics`](https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/hir_ty/src/utils.rs#L153) currently only assumes type parameters but not lifetime parameters and therefor creates incorrect index and length calculations, this PR just makes the use sites ignore LifetimeGenerics for now. This fixes the panic at least locally for me for `analysis-stats`. Funnily enough this panic prevented me from using reference search for the `args` field to fix this problem.

|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | 6845: Don't HirDisplay unknown types when displaying for source r=Veykril a=Veykril Was wondering why the add missing impl assist didn't do anything here: ![Code_JCA1Qo0V9P](https://user-images.githubusercontent.com/3757771/101990300-7af44a80-3ca6-11eb-8431-e5eb4de4e78c.png) Turns out me forgetting to set the Index::Idx type in the trait causes RA to panic due to it trying to to create an unparsable type in the `make` module. Now we get this instead which imo is definitely better to have. ![Code_MUFPJUCULY](https://user-images.githubusercontent.com/3757771/101990347-c9094e00-3ca6-11eb-9c6a-146bddf64b7c.png) Co-authored-by: Lukas Wirth <[email protected]>

I'll get to that once I start moving the lifetime reference PR to the hir. This also adds a new `hir` name type for lifetimes and labels, `hir::LifetimeName`.

* Upgrade ChalkFlorian Diebold2020-12-076-14/+126
| | | | | | | Also make overflow depth and max type size configurable through env variables. This can be helpful at least for debugging. Fixes #6628.
* Use correct, full substs for self type in implFlorian Diebold2020-12-042-1/+26
| | | | | | | | Without arbitrary self types, the self type could never refer to the method type parameters, so this wasn't a problem; but with arbitrary self types, it can. This fixes the crash from #6668; but it doesn't make method resolution work for these methods.

| | | | | | | | It's very useful when `pub` is equivalent to "this is crate's public API", let's enforce this! Ideally, we should enforce it for local `cargo test`, and only during CI, but that needs https://github.com/rust-lang/cargo/issues/5034.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 6350: Make IncorrectDiagnostic match rustc by copying rustc's code. r=popzxc a=ArifRoktim This closes #6343 and closes #6345. The old algorithm which used a `DetectedCase` enum, didn't match how rustc thinks of cases. Some inputs can be interpreted as more than 1 case depending on the situation. For example, to rustc: - `ABCD`: Can be both camel case and upper snake case - `X86_64`: Can be both camel case and upper snake case I could've made `detect_case` return a collection of `DetectedCase` and then modified the other code as such, but I think using the same code rustc uses is simpler and a surefire way to achieve the same diagnostics as rustc.
