[−][src]Struct rand_xoshiro::Xoroshiro128StarStar
A xoroshiro128** random number generator.
The xoroshiro128** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoroshiro128starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations
impl Xoroshiro128StarStar
[src]
pub fn jump(&mut self)
[src]
Jump forward, equivalently to 2^64 calls to next_u64()
.
This can be used to generate 2^64 non-overlapping subsequences for parallel computations.
use rand_xoshiro::rand_core::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();
pub fn long_jump(&mut self)
[src]
Jump forward, equivalently to 2^96 calls to next_u64()
.
This can be used to generate 2^32 starting points, from each of which
jump()
will generate 2^32 non-overlapping subsequences for parallel
distributed computations.
