Struct rand_xoshiro::Xoshiro512StarStar [−][src]
A xoshiro512** random number generator.
The xoshiro512** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.
The algorithm used here is translated from the xoshiro512starstar.c
reference source code by
David Blackman and Sebastiano Vigna.
Implementations
impl Xoshiro512StarStar
[src]
pub fn jump(&mut self)
[src]
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_xoshiro::rand_core::SeedableRng; use rand_xoshiro::Xoshiro512StarStar; let rng1 = Xoshiro512StarStar::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 2^384 calls to next_u64()
.
This can be used to generate 2^128 starting points, from each of which
jump()
will generate 2^128 non-overlapping subsequences for parallel
distributed computations.

type Seed = Seed512
Seed type, which is restricted to types mutably-dereferencable as u8
arrays (we recommend [u8; N]
