Exhaustively handle parsed attributes in CheckAttr by mejrs · Pull Request #140372 · rust-lang/rust

mejrs · 2025-04-27T19:51:27Z

This pr

Deletes the unused DiagnosticAttribute struct and variant
Comments the AttributeKind enum
The match in CheckAttrVisitor is now exhaustive for AttributeKind::Parsed.
Moved some checks around after that change

I did not thoroughly check that there's no duplicated logic between this pass and the attribute parsing but I think it's OK.

Thanks @jieyouxu . I think I read the CI error wrong and that's why I added the <> 😆

I'm sorry for the long wait, however I finally started getting time to review these so I took it back and will review today :)

I'll add this back in soon, but that's ok

I'd like to do that actually, I just thought there shouldn't be a bunch of dead code here at this time.

I agree, and feel free to. I just filed #138164, #138165 and #138291 which might help with that

Some minor comments, but looks good overall
