Merge `impl_wf_inference` (`check_mod_impl_wf`) check into coherence checking Problem here is that we call `collect_impl_trait_in_trait_types` when checking `check_mod_impl_wf` which is performed before coherence. Due to the `tcx.sess.track_errors`, since we end up reporting an error, we never actually proceed to coherence checking, where we would be emitting a more useful impl overlap error. This change means that we may report more errors in some cases, but can at least proceed far enough to leave a useful message for overlapping traits with RPITITs in them. Fixes #116982 r? types |
