🔬This is a nightly-only experimental API. (`core_intrinsics`)
Expand description

Like `cttz`, but extra-unsafe as it returns `undef` when given an `x` with value `0`.

This intrinsic does not have a stable counterpart.

## Examples

    #![feature(core_intrinsics)]

    use std::intrinsics::cttz_nonzero;

    let x = 0b0011_1000_u8;
    let num_trailing = unsafe { cttz_nonzero(x) };
    assert_eq!(num_trailing, 3);
