Struct rand_xoshiro::Xoshiro128StarStar
source · pub struct Xoshiro128StarStar { /* private fields */ }
Expand description
A xoshiro128** random number generator.
The xoshiro128** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoshiro128starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations
sourceimpl Xoshiro128StarStar
impl Xoshiro128StarStar
sourcepub fn jump(&mut self)
pub fn jump(&mut self)
Jump forward, equivalently to 2^64 calls to next_u32()
.
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();
