Description: API documentation for the Rust `swap_nonoverlapping` fn in crate `std`.
Keywords: rust, rustlang, rust-lang, swap_nonoverlapping

# Function std::ptr::swap_nonoverlapping 1.27.0[−][src]

    pub unsafe fn swap_nonoverlapping<T>(x: *mut T, y: *mut T, count: usize)

Swaps a sequence of values at two mutable locations of the same type.

# Safety

The two arguments must each point to the beginning of `count` locations of valid memory, and the two memory ranges must not overlap.

# Examples

Basic usage:

    use std::ptr;

    let mut x = [1, 2, 3, 4];
    let mut y = [7, 8, 9];

    unsafe {
        ptr::swap_nonoverlapping(x.as_mut_ptr(), y.as_mut_ptr(), 2);
    }

    assert_eq!(x, [7, 8, 3, 4]);
    assert_eq!(y, [1, 2, 9]);Run

## 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` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
