AST/HIR: Add a separate structure for labels

2018-01-22T20:13:12+00:00

Remove `impl Foo for ..` in favor of `auto trait Foo`

2018-01-13T15:48:00+00:00

No longer parse it. Remove AutoTrait variant from AST and HIR. Remove backwards compatibility lint. Remove coherence checks, they make no sense for the new syntax. Remove from rustdoc.

Resurrecting #33135

2017-12-28T16:32:05+00:00

Started rebasing @sgrif's PR #33135 off of current master. (Well, actually merging it into a new branch based off current master.) The following files still need to be fixed or at least reviewed: - `src/libsyntax/ext/tt/macro_parser.rs`: calls `Parser::parse_lifetime`, which doesn't exist anymore - `src/libsyntax/parse/parser.rs`: @sgrif added an error message to `Parser::parse_lifetime`. Code has since been refactored, so I just took it out for now. - `src/libsyntax/ext/tt/transcribe.rs`: This code has been refactored bigtime. Not sure whether @sgrif's changes here are still necessary. Took it out for this commit.

Auto merge of #46732 - estebank:silence-recovered-blocks, r=petrochenkov

2017-12-22T07:22:33+00:00

Do not emit type errors on recovered blocks When a parse error occurs on a block, the parser will recover and create a block with the statements collected until that point. Now a flag stating that a recovery has been performed in this block is propagated so that the type checker knows that the type of the block (which will be identified as `()`) shouldn't be checked against the expectation to reduce the amount of irrelevant diagnostic errors shown to the user. Fix #44579.

Add GenericParam, refactor Generics in ast, hir, rustdoc

2017-12-21T12:38:10+00:00

The Generics now contain one Vec of an enum for the generic parameters, rather than two separate Vec's for lifetime and type parameters. Additionally, places that previously used Vec now use Vec instead.
