Struct rand_xoshiro::Xoroshiro128StarStar
source · pub struct Xoroshiro128StarStar { /* private fields */ }
Expand description
A xoroshiro128** random number generator.
The xoroshiro128** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoroshiro128starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations
sourceimpl Xoroshiro128StarStar
impl Xoroshiro128StarStar
sourcepub fn jump(&mut self)
pub fn jump(&mut self)
Jump forward, equivalently to 2^64 calls to next_u64()
.
This can be used to generate 2^64 non-overlapping subsequences for parallel computations.
use rand::SeedableRng;
use rand_xoshiro::Xoroshiro128StarStar;
let rng1 = Xoroshiro128StarStar::seed_from_u64(0);
let mut rng2 = rng1.clone();
rng2.jump();
let mut rng3 = rng2.clone();
rng3.jump();
