Struct xoshiro::Xoshiro512Plus [−][src]
pub struct Xoshiro512Plus { /* fields omitted */ }
A xoshiro512+ random number generator.
The xoshiro512+ 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 xoshiro512plus.c
reference source code by
David Blackman and Sebastiano Vigna.
Methods
impl Xoshiro512Plus
[src]
impl Xoshiro512Plus
pub fn from_seed_u64(seed: u64) -> Xoshiro512Plus
[src]
pub fn from_seed_u64(seed: u64) -> Xoshiro512Plus
Seed a Xoshiro512Plus
from a u64
using SplitMix64
.
pub fn jump(&mut self)
[src]
pub fn jump(&mut self)
Jump forward, equivalently to 2^256 calls to next_u64()
.
This can be used to generate 2^256 non-overlapping subsequences for parallel computations.
use rand::SeedableRng; use xoshiro::Xoshiro512Plus; let rng1 = Xoshiro512Plus::from_seed_u64(0); let mut rng2 = rng1.clone(); rng2.jump(); let mut rng3 = rng2.clone(); rng3.jump();
