Trait std::clone::Clone
[−]
[src]
pub trait Clone {
fn clone(&self) -> Self;
fn clone_from(&mut self, source: &Self) { ... }
}A common trait for cloning an object.
This trait can be used with #[derive].
Required Methods
fn clone(&self) -> Self
Returns a copy of the value.
Examples
fn main() { let hello = "Hello"; // &str implements Clone assert_eq!("Hello", hello.clone()); }let hello = "Hello"; // &str implements Clone assert_eq!("Hello", hello.clone());
Provided Methods
fn clone_from(&mut self, source: &Self)
Performs copy-assignment from source.
a.clone_from(&b) is equivalent to a = b.clone() in functionality,
but can be overridden to reuse the resources of a to avoid unnecessary
allocations.
