# Function std::mem::swap [−] [src]

    pub fn swap<T>(x: &mut T, y: &mut T)

Swap the values at two mutable locations of the same type, without deinitializing or copying either one.

# Examples

fn main() { use std::mem; let x = &mut 5; let y = &mut 42; mem::swap(x, y); assert_eq!(42, *x); assert_eq!(5, *y); }

    use std::mem;

    let x = &mut 5;
    let y = &mut 42;

    mem::swap(x, y);

    assert_eq!(42, *x);
    assert_eq!(5, *y);

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize`)
