Crate mersenne_twister

Mersenne Twister

A pure rust port of the Mersenne Twister pseudorandom number generator.

THESE ALGORITHMS ARE NOT APPROPRIATE FOR CRYPTOGRAPHIC USE.

Usage

If your application does not require a specific Mersenne Twister flavor, you can use the default one for your target platform this way:

#![feature(rand)]
extern crate mersenne_twister;
use mersenne_twister::MersenneTwister;
use std::rand::{Rng, SeedableRng};

fn main() {
    // Get a seed somehow.
    let seed: u64 = 0x123456789abcdef;
    // Create the default RNG.
    let mut rng: MersenneTwister = SeedableRng::from_seed(seed);

    // start grabbing randomness from rng...
}

Or if you want to use the default (fixed) seeds:

use std::default::Default;
let mut rng: MersenneTwister = Default::default();

Portability

Note that MT19937 and MT19937_64 are not identical algorithms, despite their similar names. They produce different output streams when given the same seed. You will need to pick a specific flavor of the algorithm if portable reproducibility is important to you.

Structs

MT19937	The 32-bit flavor of the Mersenne Twister pseudorandom number generator.
MT19937_64	The 64-bit flavor of the Mersenne Twister pseudorandom number generator.
