Expand description

Reverses the bytes in an integer type T.

Note that, unlike most intrinsics, this is safe to call; it does not require an unsafe block. Therefore, implementations must not require the user to uphold any safety invariants.

The stabilized versions of this intrinsic are available on the integer primitives via the swap_bytes method. For example, u32::swap_bytes
