Recover from incorrectly ordered/duplicated function keywords Fixes #115714
2023-11-07Auto merge of #117297 - clubby789:fn-trait-missing-paren, r=TaKO8Kibors-0/+27
Give a better diagnostic for missing parens in Fn* bounds Fixes #108109 It would be nice to try and recover here, but I'm not sure it's worth the effort, especially as the bounds on the recovered function would be incorrect.

2023-10-12Detect ruby-style closure in parserEsteban Küber-2/+17
When parsing a closure without a body that is surrounded by a block, suggest moving the opening brace after the closure head. Fix #116608.

2023-05-27Rollup merge of #111181 - bvanjoi:fix-issue-111148, r=davidtwcoMatthias Krüger-0/+10
fix(parse): return unpected when current token is EOF close https://github.com/rust-lang/rust/issues/111148 #111148 panic occurred because [FatalError.raise()](https://github.com/bvanjoi/rust/blob/master/compiler/rustc_parse/src/parser/mod.rs#LL540C3-L540C3) was encountered which caused by `Eof` and `Pound`(the last token) had same span, when parsing `#` in `fn a<<i<Y<w<>#`. <img width="825" alt="image" src="https://user-images.githubusercontent.com/30187863/236612589-9e2c6a0b-18cd-408c-b636-c12a51cbcf1c.png"> There are a few ways to solve this problem: - Change the action assign for [self.last_unexpected_token_span](https://github.com/rust-lang/rust/blob/master/compiler/rustc_parse/src/parser/diagnostics.rs#L592), for example, if current token is `Eof`, then return Error directly. - Avoid triggering the `FatalError` when the current token is `Eof`. I have chosen the second option because executing `expected_one_of_not_found` when the token is `Eof` but not in `ediable` seems reasonable.

My type ascription Oh rip it out Ah If you think we live too much then You can sacrifice diagnostics Don't mix your garbage Into my syntax So many weird hacks keep diagnostics alive Yet I don't even step outside So many bad diagnostics keep tyasc alive Yet tyasc doesn't even bother to survive!
