Struct mersenne_twister::MT19937_64
[−]
[src]
pub struct MT19937_64 { /* fields omitted */ }
The 64-bit flavor of the Mersenne Twister pseudorandom number generator.
Methods
impl MT19937_64
[src]
fn new_unseeded() -> MT19937_64
[src]
Create a new Mersenne Twister random number generator using the default fixed seed.
fn recover(samples: &[u64]) -> MT19937_64
[src]
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.
