* Upgrade ChalkFlorian Diebold2020-12-071-0/+43
| | | | | | | 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 Diebold2020-12-041-0/+19
| | | | | | | | 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.

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]>
