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[E0277]: the trait bound `Foo: Qux` is not satisfied in `impl Future<Output = ()>`

--> $DIR/issue-64130-3-other.rs:25:12

|
|
LL | async fn bar() {

|
| ^^^^^ unsatisfied trait bound

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

LL | struct Foo;
|
|
| ^^^^^^^^^^
|
|
note: future does not implement `Qux` as this value is used across an await

|
|
LL | let x = Foo;

|
| - has type `Foo` which does not implement `Qux`

LL | baz().await;

| ^^^^^ await occurs here, with `x` maybe used later
|

note: required by a bound in `is_qux`
