When encountering an unmet trait bound, point at local type that doesn't implement the trait: ``` error[E0277]: the trait bound `Bar<T>: Foo` is not satisfied --> $DIR/issue-64855.rs:9:19 | LL | pub struct Bar<T>(<Self as Foo>::Type) where Self: ; | ^^^^^^^^^^^^^^^^^^^ unsatisfied trait bound | help: the trait `Foo` is not implemented for `Bar<T>` --> $DIR/issue-64855.rs:9:1 | LL | pub struct Bar<T>(<Self as Foo>::Type) where Self: ; | ^^^^^^^^^^^^^^^^^ ```
