| error[E0277]: the trait bound `U: Eq` is not satisfied | |

| | ^^^^^^^^^^^^^^^ the trait `Eq` is not implemented for `U` | |
| | | |
| note: required by a bound in `Foo` | |

| LL | trait Foo<'a, T: Eq + 'a> { } | |
| | ^^ required by this bound in `Foo` | |
| help: consider restricting type parameter `U` with trait `Eq` | |
