2019-07-01Auto merge of #61682 - Centril:stabilize-type_alias_enum_variants, ↵bors-1/+1
r=petrochenkov Stabilize `type_alias_enum_variants` in Rust 1.37.0 Stabilize `#![feature(type_alias_enum_variants)]` which allows type-relative resolution with highest priority to `enum` variants in both expression and pattern contexts. For example, you may now write: ```rust enum Option<T> { None, Some(T), } type OptAlias<T> = Option<T>; fn work_on_alias(x: Option<u8>) -> u8 { match x { OptAlias::Some(y) => y + 1, OptAlias::None => 0, } } ``` Closes https://github.com/rust-lang/rfcs/issues/2218 Closes https://github.com/rust-lang/rust/issues/52118 r? @petrochenkov

2019-06-24Auto merge of #62075 - Centril:guardless-match-arms, r=petrochenkovbors-1/+1
Remove `ast::Guard` With the introduction of `ast::ExprKind::Let` in https://github.com/rust-lang/rust/pull/60861, the `ast::Guard` structure is now redundant in terms of representing [`if let` guards](https://github.com/rust-lang/rust/issues/51114) in AST since it can be represented by `ExprKind::Let` syntactically. Therefore, we remove `ast::Guard` here. However, we keep `hir::Guard` because the semantic representation is a different matter and this story is more unclear right now (might involve `goto 'arm` in HIR or something...). r? @petrochenkov

2019-05-30Auto merge of #61253 - nnethercote:avoid-hygiene_data-lookups, r=petrochenkovbors-5/+5
Avoid `hygiene_data` lookups These commits mostly introduce compound operations that allow two close adjacent `hygiene_data` lookups to be combined. r? @petrochenkov

We are going to uniform the terminology of all associated items. Methods that may or may not have `self` are called "associated functions". Because `AssociatedFn` is a bit long, we rename `Associated` to `Assoc`.
