[−][src]Struct rand_xoshiro::Xoshiro128Plus
A xoshiro128+ random number generator.
The xoshiro128+ 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 xoshiro128starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Methods
impl Xoshiro128Plus
[src]
pub fn jump(&mut self)
[src]
Jump forward, equivalently to 2^64 calls to next_u32()
.
This can be used to generate 2^64 non-overlapping subsequences for parallel computations.
use rand::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();

impl SeedableRng for Xoshiro128Plus
[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]) -> Xoshiro128Plus
[src]
Create a new Xoshiro128Plus
. If seed
is entirely 0, it will be
mapped to a different seed.
fn seed_from_u64(seed: u64) -> Xoshiro128Plus
[src]
Seed a Xoshiro128Plus
from a u64
using SplitMix64
.
fn from_rng<R>(rng: R) -> Result<Self, Error> where
R: RngCore,
[src]
R: RngCore,
Create a new PRNG seeded from another Rng
