| error[E0478]: lifetime bound not satisfied |
There was a problem hiding this comment.
This error is now not emitted since we return ErrorGuaranteed in compare_type_predicate_entailment, which means we never get to check_type_bounds which is where this error is reported.

The changes look good but I'm not familiar with the code so I'll r? types for further review. |

…n-err, r=estebank Make trait/impl `where` clause mismatch on region error a bit more actionable Improve `where` clause suggestions for GATs/methods that have incompatible region predicates in their `where` clauses. Also addresses this diagnostic that went away rust-lang#106129 (comment)

…s, r=BoxyUwU Some `compare_method` tweaks 1. Make some of the comparison functions' names more regular 2. Reduce pub scope of some of the things in `compare_method` ~3. Remove some unnecessary opaque type handling code -- `InferCtxt` already is in a mode that doesn't define opaque types~ * moved to a different PR 4. Bubble up `ErrorGuaranteed` for region constraint errors in `compare_method` - Improves a redundant error message in one unit test. 5. Move the `compare_method` module to have a more general name, since it's more like `compare_impl_item` :) 6. Rename `collect_trait_impl_trait_tys`
