Function bitwise::word::isolate_least_significant_zero

pub fn isolate_least_significant_zero<T: Word>(x: T) -> T

Returns mask with the least significant zero bit of x set to 1.

All other bits of the mask are set to zero. If x contains only set bits, returns 0.

Intrinsics:

• TBM: blcic (or: blci, not).

Examples

use bitwise::word::*;

let n = 0b0101;
let s = 0b0010;

assert_eq!(n.isolate_least_significant_zero(), s);
assert_eq!(isolate_least_significant_zero(0b1111_1111u8), 0u8);
