…e-types, r=Centril Point at opaque and closure type definitions in type errors Fixes rust-lang#57266, fixes rust-lang#67117.
…Jung Reduce special treatment for zsts addresses rust-lang#67467 (comment) cc @RalfJung
Parse the syntax described in RFC 2632 This adds support for both `impl const Trait for Ty` and `?const Trait` bound syntax from rust-lang/rfcs#2632 to the parser. For now, both modifiers end up in a newly-added `constness` field on `ast::TraitRef`, although this may change once the implementation is fleshed out. I was planning on using `delay_span_bug` when this syntax is encountered during lowering, but I can't write `should-ice` UI tests. I emit a normal error instead, which causes duplicates when the feature gate is not enabled (see the `.stderr` files for the feature gate tests). Not sure what the desired approach is; Maybe just do nothing when the syntax is encountered with the feature gate is enabled? @oli-obk I went with `const_trait_impl` and `const_trait_bound_opt_out` for the names of these features. Are these to your liking? cc rust-lang#67792 rust-lang#67794 r? @Centril
…enkov rustc_ast_lowering: misc cleanup & rustc dep reductions - The first two commits do some code simplification. - The next three do some file splitting (getting `lib.rs` below the 3kloc tidy lint). - The remaining commits reduce the number of `rustc::` imports. This works towards making lowering independent of the `rustc` crate. r? @oli-obk cc @Zoxc
Extend support of `_` in type parameters
- Account for `impl Trait<_>`.
- Provide a reasonable `Span` for empty `Generics` in `impl`s.
- Account for `fn foo<_>(_: _) {}` to suggest `fn foo<T>(_: T) {}`.
- Fix rust-lang#67995. Follow up to rust-lang#67597.
expect `fn` after `const unsafe` / `const extern` Fixes rust-lang#68062 r? @estebank @petrochenkov cc @Aaron1011
