As a workaround for the full `#[refine]` semantics not being implemented yet, forbit returning a concrete future type like `Box<dyn Future>` or a manually implemented Future. `-> impl Future` is still permitted; while that can also cause accidental refinement, that's behind a different feature gate (`return_position_impl_trait_in_trait`) and that problem exists regardless of whether the trait method is async, so will have to be solved more generally. Fixes rust-lang#102745
…f-id, r=estebank Use impl's def id when calculating type to specify in UFCS Fixes rust-lang#104327 Fixes rust-lang#104328 Also addresses rust-lang#102670 (comment)
…ler-errors Ensure async trait impls are async (or otherwise return an opaque type) As a workaround for the full `#[refine]` semantics not being implemented yet, forbit returning a concrete future type like `Box<dyn Future>` or a manually implemented Future. `-> impl Future` is still permitted; while that can also cause accidental refinement, that's behind a different feature gate (`return_position_impl_trait_in_trait`) and that problem exists regardless of whether the trait method is async, so will have to be solved more generally.

…env-2, r=estebank Highlight conflicting param-env candidates, again Un-reverts rust-lang#98794 (i.e. reverts rust-lang#99290). The previous time I attempted to land this PR, it was because of an incremental issue (rust-lang#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 rust-lang#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 rust-lang#105131. Fixes (again) rust-lang#98786

…le, r=davidtwco Auto traits in `dyn Trait + Auto` are suggestable Not sure why I had made the `IsSuggestableVisitor` have that rule to not consider `dyn Trait + Auto` to be suggestable. It's possible that this was done because of the fact that we don't print the right parentheses for `&(dyn Trait + Auto)`, but that's a problem with printing these types in general that we probably have tracked somewhere else...
