Trait bitintr::Pext
[−]
[src]
pub trait Pext { fn pext(self, mask: Self) -> Self; }
Parallel bits extract
Required Methods
fn pext(self, mask: Self) -> Self
Parallel bits extract.
Gathers the bits of x
specified by the mask_
into the contiguous
low order bit positions of the result.
The remaining high-order bits of the result are set to zero.
Keywords: Parallel bits extract, gather bits.
