Trait std::borrow::ToOwned

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