Trait boo::ToOwned [−] [src]

pub trait ToOwned {
    type Owned: Borrow<Self>;
    fn to_owned(&self) -> Self::Owned;

    fn clone_into(&self, target: &mut Self::Owned) { ... }
}

A generalization of Clone to borrowed data.

Some types make it possible to go from borrowed to owned, usually by implementing the Clone trait. But Clone works only for going from &T to T. The ToOwned trait generalizes Clone to construct owned data from any borrow of a given type.

Associated Types
