Struct mersenne_twister::MT19937_64

pub struct MT19937_64 { /* fields omitted */ }

The 64-bit flavor of the Mersenne Twister pseudorandom number generator.

Methods

impl MT19937_64

fn new_unseeded() -> MT19937_64

Create a new Mersenne Twister random number generator using the default fixed seed.

fn recover(samples: &[u64]) -> MT19937_64

Recover the internal state of a Mersenne Twister instance from 312 consecutive outputs of the algorithm.

The returned MT19937_64 is guaranteed to identically reproduce subsequent outputs of the RNG that was sampled.

Panics if the length of the slice is not exactly 312.
