Some changes occurred in compiler/rustc_attr_parsing |
|
An opinionated PR, this one... sorry there are a bunch of changes in a single commit, it was hard to separate them out. Removing the functions that returned tuples was important, they got in the way of other changes. |
|
I see, well I'll take a look :) |

This helps with #137978. |

hm, would you mind at least making the removals from parser.rs a separate commit. I'm not 100% sure I agree with those removals. I intended those APIs to be for all the future attribute parsers that will be converted to a dedicated parser implementation. The reason I am kind of okay with it is because that some of those APIs were made before I allowed easy matching on attribute parsers, which really is a better API so maybe that's what we should switch to. But that'd still be nicer to discuss/refer to if it were a separate commit. I also quickly want to see whether some of my open but blocked PRs relied on those APIs just to see if I had very good reasons for them but I doubt it. |

I have split it into two commits. |
|
The first commit is blocking another PR. That's the one I reviewed and am happy with merging (maybe after some nitpicks are addressed). I think some of those unwraps might be unnecessary. I can take one more look tomorrow if you decide to change something and then we can merge it. The other, second, commit I have some doubts about right now, which I expressed earlier. If it helps unblock another PR, feel free to refile the second commit in another PR and assign me, then I'll take a look later when I have more time. Rust Week planning is taking a lot. Good night! |
To get rid of the `Ident::empty` uses. This requires introducing `PathParser::word_sym`, as an alternative to `PathParser::word`.
By using `@` patterns more. Also, use `Symbol` more in a couple of errors to avoid some unnecessary conversions to strings. This even removes a lifetime.

I have removed the original second commit with the API changes; we can try again with those in a follow-up PR. I have added a new second commit that avoids the unwraps and does a couple of other small related improvements. @rustbot ready |
To remove the last remaining
Ident::emptyuses.r? @jdonszelmann
