bors 397b66e77b Auto merge of #105285 - compiler-errors:conflicting-param-env-2, r=estebank ... Highlight conflicting param-env candidates, again Un-reverts #98794 (i.e. reverts #99290). The previous time I attempted to land this PR, it was because of an incremental issue (#99233). The repro instructions in the issue is no longer manifest the ICE -- I think it's because this ambiguity code was refactored (I think by `@lcnr)` to no longer store the ambiguities in the fulfillment error, but instead recompute them on the fly. The main motivation for trying to re-land this is that it fixes #105131 by highlighting the root-cause of the issue, which is conflicting param-env candidates: ``` error[E0283]: type annotations needed: cannot satisfy `Self: Gen<'source>` | note: multiple `impl`s or `where` clauses satisfying `Self: Gen<'source>` found --> $DIR/conflicting-bounds.rs:3:1 | LL | pub trait Gen<'source> { | ^^^^^^^^^^^^^^^^^^^^^^ ... LL | Self: for<'s> Gen<'s, Output = T>; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ error: aborting due to previous error For more information about this error, try `rustc --explain E0283`. ``` Fixes #105131. Fixes (again) #98786		2022-12-15 11:11:49 +00:00
