Here's some concern about implementation detail: - Chalk doesn't support generator type yet. - Adding generator type as a brand new type (ctor) can be complex and need to *re-introduced* builtin impls. (Like how we implement closures before native closure support of chalk, which is already removed in #5401 ) - The output type of async block should be known after type inference of the whole body. - We cannot directly get the type from source like return-positon-impl-trait. But we still need to provide trait bounds when chalk asking for `opaque_ty_data`. - During the inference, the output type of async block can be temporary unknown and participate the later inference. `let a = async { None }; let _: i32 = a.await.unwrap();` So in this PR, the type of async blocks is inferred as an opaque type parameterized by the `Future::Output` type it should be, like what we do with closure type. And it really works now. Well, I still have some questions: - The bounds `AsyncBlockImplType<T>: Future<Output = T>` is currently generated in `opaque_ty_data`. I'm not sure if we should put this code here. - Type of async block is now rendered as `impl Future<Output = OutputType>`. Do we need to special display to hint that it's a async block? Note that closure type has its special format, instead of `impl Fn(..) -> ..` or function type. Co-authored-by: oxalica <[email protected]>

|\ \ | |/ |/| | | | | | | | | | | | | | | 5968: Lookup ADT and associated type names for chalk debugging / tweak chalk interner r=flodiebold a=nathanwhit This PR improves the chalk program writing integration by looking up the names for ADTs and associated types, making the output much more readable. There are also a few small changes to the interner, which gives some nice performance improvements. We clone `Ty`s and `ProgramClause`s relatively often in chalk, so wrapping them in `Arc`s is a perf win. This takes the time for performing type inference on the rust-analyzer codebase from 40s to 33s on my machine. Co-authored-by: Nathan Whitaker <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 5682: Add an option to disable diagnostics r=matklad a=popzxc As far as I know, currently it's not possible to disable a selected type of diagnostics provided by `rust-analyzer`. This causes an inconvenient situation with a false-positive warnings: you either have to disable all the diagnostics, or you have to ignore these warnings. There are some open issues related to this problem, e.g.: https://github.com/rust-analyzer/rust-analyzer/issues/5412, https://github.com/rust-analyzer/rust-analyzer/issues/5502 This PR attempts to make it possible to selectively disable some diagnostics on per-project basis.
