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.
The resulting type after obtaining ownership.
Creates owned data from borrowed data, usually by cloning.
Basic usage:
let s: &str = "a";
let ss: String = s.to_owned();
let v: &[i32] = &[1, 2];
let vv: Vec<i32> = v.to_owned();

#41263)
Uses borrowed data to replace owned data, usually by cloning.
This is borrow-generalized version of Clone::clone_from
.
Basic usage:
let mut s: String = String::new();
"hello".clone_into(&mut s);
let mut v: Vec<i32> = Vec::new();
[1, 2][..].clone_into(&mut v);
