| LL | impl<Foo> Deref for Foo { } |
| | ^^^^^^^^^^^^^^^^^^^^^^^ |
| | |
| = note: conflicting implementation in crate `core`: |
| - impl<T> Deref for &T |
| where T: ?Sized; |

| error[E0210]: type parameter `Foo` must be used as the type parameter for some local type (e.g., `MyStruct<Foo>`) |
| --> $DIR/issue-28981.rs:5:6 |

| LL | impl<Foo> Deref for Foo { } |
| | ^^^ type parameter `Foo` must be used as the type parameter for some local type |
| | |
| = note: implementing a foreign trait is only possible if at least one of the types for which is it implemented is local |
| = note: only traits defined in the current crate can be implemented for a type parameter |
