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
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.
