Trait alloc::borrow::ToOwned 1.0.0[−][src]
pub trait ToOwned { type Owned: Borrow<Self>; #[must_use = "cloning is often expensive and is not expected to have side effects"] fn to_owned(&self) -> Self::Owned; fn clone_into(&self, target: &mut Self::Owned) { ... } }
Expand description
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.
