make `type_flags(ReError) & HAS_ERROR` #122749

aliemjay · 2024-03-19T21:35:19Z

Self-explanatory. TypeVisitableExt::references_error(ReError) incorrectly returned false.

This is removed to avoid an ICE in tests/ui/type-alias-impl-trait/under-binder.rs. I'll rewrite it anyway in #116891.

Do you know why this error occurs?

Would like some explanations for why these error messages start appearing, but I agree that this is the right approach in general. I don't think they necessarily should be fixed, but am curious nonetheless.

And this one too, do you know why it occurs?

I'll look into it.

We don't register opaques that reference errors: https://github.com/rust-lang/rust/blame/a128516cf9de352ae1f9d430ed730363c7ca3c0c/compiler/rustc_infer/src/infer/opaque_types/mod.rs#L97.

I changed it in a later commit to register hidden types unconditionally.

Cool, I like this consistency fix
