[][src]Struct rand_xoshiro::Xoshiro256PlusPlus

pub struct Xoshiro256PlusPlus { /* 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 xoshiro256plusplus.c reference source code by David Blackman and Sebastiano Vigna.


impl Xoshiro256PlusPlus[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::Xoshiro256PlusPlus;

let rng1 = Xoshiro256PlusPlus::seed_from_u64(0);
let mut rng2 = rng1.clone();
let mut rng3 = rng2.clone();

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 Xoshiro256PlusPlus[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

pub fn from_seed(seed: [u8; 32]) -> Xoshiro256PlusPlus[src]

Create a new Xoshiro256PlusPlus. If seed is entirely 0, it will be mapped to a different seed.

pub fn seed_from_u64(seed: u64) -> Xoshiro256PlusPlus[src]

Seed a Xoshiro256PlusPlus from a u64 using SplitMix64.
