Struct rand_xoshiro::Xoshiro512StarStar
source · pub struct Xoshiro512StarStar { /* private fields */ }
Expand description
A xoshiro512** random number generator.
The xoshiro512** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoshiro512starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations§
source§impl Xoshiro512StarStar
impl Xoshiro512StarStar
sourcepub fn jump(&mut self)
pub fn jump(&mut self)
Jump forward, equivalently to 2^256 calls to next_u64()
.
This can be used to generate 2^256 non-overlapping subsequences for parallel computations.
use rand::SeedableRng;
use rand_xoshiro::Xoshiro512StarStar;
let rng1 = Xoshiro512StarStar::seed_from_u64(0);
let mut rng2 = rng1.clone();
rng2.jump();
let mut rng3 = rng2.clone();
rng3.jump();
