Struct rand_xoshiro::Xoshiro128PlusPlus [−][src]
pub struct Xoshiro128PlusPlus { /* fields omitted */ }
Expand description
A xoshiro128++ random number generator.
The xoshiro128++ algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoshiro128plusplus.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations
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_xoshiro::rand_core::SeedableRng;
use rand_xoshiro::Xoroshiro128PlusPlus;
let rng1 = Xoroshiro128PlusPlus::seed_from_u64(0);
let mut rng2 = rng1.clone();
rng2.jump();
let mut rng3 = rng2.clone();
rng3.jump();

is entirely 0, it will be
mapped to a different seed.
