[][src]Struct rand_xoshiro::Xoshiro256StarStar

pub struct Xoshiro256StarStar { /* fields omitted */ }

A xoshiro256** random number generator.

The xoshiro256** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.

The algorithm used here is translated from the xoshiro256starstar.c reference source code by David Blackman and Sebastiano Vigna.

Methods

impl Xoshiro256StarStar[src]

pub fn jump(&mut self)[src]

Jump forward, equivalently to 2^128 calls to next_u64().

This can be used to generate 2^128 non-overlapping subsequences for parallel computations.

use rand_xoshiro::rand_core::SeedableRng;
use rand_xoshiro::Xoshiro256StarStar;

let rng1 = Xoshiro256StarStar::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 2^192 calls to next_u64().

This can be used to generate 2^64 starting points, from each of which jump() will generate 2^64 non-overlapping subsequences for parallel distributed computations.

impl SeedableRng for Xoshiro256StarStar[src]

type Seed = [u8; 32]

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; 32]) -> Xoshiro256StarStar[src]
