)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);
