pub static UNUSED_ASSOCIATED_TYPE_BOUNDS: &'static Lint
Expand description
The unused_associated_type_bounds
lint is emitted when an
associated type bound is added to a trait object, but the associated
type has a where Self: Sized
bound, and is thus unavailable on the
trait object anyway.
§Example
trait Foo {
type Bar where Self: Sized;
}
type Mop = dyn Foo<Bar = ()>;
{{produces}}
§Explanation
Just like methods with Self: Sized
bounds are unavailable on trait
objects, associated types can be removed from the trait object.
