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.
