Struct rand_xoshiro::Xoroshiro128StarStar[][src]

pub struct Xoroshiro128StarStar { /* fields omitted */ }

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

impl Xoroshiro128StarStar[src]

pub fn jump(&mut self)[src]

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_xoshiro::rand_core::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();

pub fn long_jump(&mut self)[src]

Jump forward, equivalently to 2^96 calls to next_u64().

This can be used to generate 2^32 starting points, from each of which jump() will generate 2^32 non-overlapping subsequences for parallel distributed computations.

impl RngCore for Xoroshiro128StarStar[src]

impl SeedableRng for Xoroshiro128StarStar[src]

type Seed = [u8; 16]

Seed type, which is restricted to types mutably-dereferencable as u8 arrays (we recommend [u8; N] for some N). Read more

fn from_seed(seed: [u8; 16]) -> Xoroshiro128StarStar[src]

Create a new Xoroshiro128StarStar. If seed is entirely 0, it will be mapped to a different seed.

fn seed_from_u64(seed: u64) -> Xoroshiro128StarStar[src]

Seed a Xoroshiro128StarStar from a u64 using SplitMix64.
