[][src]Struct rand_xoshiro::Xoshiro256Plus

pub struct Xoshiro256Plus { /* fields omitted */ }

A xoshiro256+ random number generator.

The xoshiro256+ algorithm is not suitable for cryptographic purposes, but is very fast and has good statistical properties, besides a low linear complexity in the lowest bits.

The algorithm used here is translated from the xoshiro256plus.c reference source code by David Blackman and Sebastiano Vigna.


impl Xoshiro256Plus[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::Xoshiro256Plus;

let rng1 = Xoshiro256Plus::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 Xoshiro256Plus[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]) -> Xoshiro256Plus[src]

Create a new Xoshiro256Plus. If seed is entirely 0, it will be mapped to a different seed.

fn seed_from_u64(seed: u64) -> Xoshiro256Plus[src]

Seed a Xoshiro256Plus from a u64 using SplitMix64.
