* | Ignore type bindings in generic_predicates_for_paramFlorian Diebold2021-03-211-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows us to handle more cases without a query cycle, which includes certain cases that rustc accepted. That in turn means we avoid triggering salsa-rs/salsa#257 on valid code (it will still happen if the user writes an actual cycle). We actually accept more definitions than rustc now; that's because rustc only ignores bindings when looking up super traits, whereas we now also ignore them when looking for predicates to disambiguate associated type shorthand. We could introduce a separate query for super traits if necessary, but for now I think this should be fine.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5971: Implement async blocks r=flodiebold a=oxalica Fix #4018 @flodiebold already gave a generic guide in the issue. 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]>
