[−][src]Struct swar::Bits64
This is used when every 64
bits is a number stored in parallel.
Methods
impl Bits64<u128>
[src]
pub fn from_element(e: u128) -> Self
[src]
Spread a single value out to each element. Must be able to fit.
use swar::*; assert_eq!(Bits64::from_element(0xFEED_FACE_CAFE_BEEF), Bits64(0xFEED_FACE_CAFE_BEEF_FEED_FACE_CAFE_BEEF));
pub fn sum_weight2(self) -> Bits128<u128>
[src]
pub fn hwd(self, other: Self) -> Self
[src]
This computes the hamming weight distance from hamming weights.
use swar::*; let bits = 64; for a in 0u128..=bits as u128 { for b in 0u128..=bits as u128 { let aa = Bits64(a | a << bits); let bb = Bits64(b | b << bits); let out = aa.hwd(bb); let diff = (a as i128 - b as i128).abs() as u128; let expected = Bits64(diff | diff << bits); assert_eq!(out, expected); } }
pub fn split(self) -> (Bits64x128<u128>, Bits64x128<u128>)
