Trait bitintr::Pdep

pub trait Pdep {
    fn pdep(self, mask: Self) -> Self;
}

Parallel bits deposit

Required methods

fn pdep(self, mask: Self) -> Self

Parallel bits deposit.

Scatter contiguous low order bits of x to the result at the positions specified by the mask.

All other bits (bits not set in the mask) of the result are set to zero.

Keywords: Parallel bits deposit, scatter bits.

let m1 = 0b1110_1011_1110_1111u16;
let s1 = 0b1110_1001_0010_0011u16;

assert_eq!(n.pdep(m0), s0);
assert_eq!(n.pdep(m1), s1);
