Trait collections::borrow::ToOwned
[−]
[src]
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.

Creates owned data from borrowed data, usually by cloning.
Examples
Basic usage:
fn main() { let s = "a"; // &str let ss = s.to_owned(); // String let v = &[1, 2]; // slice let vv = v.to_owned(); // Vec }let s = "a"; // &str let ss = s.to_owned(); // String let v = &[1, 2]; // slice let vv = v.to_owned(); // Vec
