Struct mersenne_twister::MT19937

pub struct MT19937 {
    // some fields omitted
}

The 32-bit flavor of the Mersenne Twister pseudorandom number generator.

Methods

impl MT19937

fn new_unseeded() -> MT19937

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

fn recover(samples: &[u32]) -> MT19937

Recover the internal state of a Mersenne Twister instance from 624 consecutive outputs of the algorithm.

The returned MT19937 is guaranteed to identically reproduce subsequent outputs of the RNG that was sampled. This is why one does not use Mersenne Twister in cryptography.

Panics if the length of the slice is not exactly 624.
