Struct rand_xoshiro::Xoshiro512Plus [−][src]
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.
Implementations
impl Xoshiro512Plus
[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::Xoshiro512Plus; let rng1 = Xoshiro512Plus::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.
