Esteban Kuber 3aac307ca6 Mention implementers of unsatisfied trait ... When encountering an unsatisfied trait bound, if there are no other suggestions, mention all the types that *do* implement that trait: ``` error[E0277]: the trait bound `f32: Foo` is not satisfied --> $DIR/impl_wf.rs:22:6 | LL | impl Baz<f32> for f32 { } | ^^^^^^^^ the trait `Foo` is not implemented for `f32` | = help: the following other types implement trait `Foo`: Option<T> i32 str note: required by a bound in `Baz` --> $DIR/impl_wf.rs:18:31 | LL | trait Baz<U: ?Sized> where U: Foo { } | ^^^ required by this bound in `Baz` ``` Mention implementers of traits in `ImplObligation`s. Do not mention other `impl`s for closures, ranges and `?`.		2022-04-04 21:01:42 +00:00
