Trait rustc_data_structures::owning_ref::IntoErased

pub unsafe trait IntoErased<'a> {
    type Erased;

    fn into_erased(self) -> Self::Erased;
}

Helper trait for erasing the concrete type of what an owner dereferences to, for example Box<T> -> Box<Erased>. This would be unneeded with higher kinded types support in the language.

Required Associated Types

type Erased

Owner with the dereference type substituted to Erased.

Required Methods

fn into_erased(self) -> Self::Erased

Performs the type erasure.
