Struct mersenne_twister::MT19937_64

pub struct MT19937_64 {
    // some 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. This is why one does not use Mersenne Twister in cryptography.

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