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: ; | ^^^^^^^^^^^^^^^^^ ```

error: future cannot be sent between threads safely

LL | is_send(bar());

help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `Foo`

LL | struct Foo;

note: future is not `Send` as this value is used across an await

LL | let x = Foo;

note: required by a bound in `is_send`
