Esteban Küber 049c32797b On E0277, point at type that doesn't implement bound 
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: ;
   | ^^^^^^^^^^^^^^^^^
