rand_mt

Implemenents a selection of Mersenne Twister random number generators.

A very fast random number generator of period 219937-1. (Makoto Matsumoto, 1997).

The Mersenne Twister algorithms are not suitable for cryptographic uses, but are ubiquitous. See the Mersenne Twister website. A variant of Mersenne Twister is the default PRNG in Ruby.

This crate optionally depends on rand_core and implements RngCore on the RNGs in this crate.

Usage

Add this to your Cargo.toml:

[dependencies]
rand_mt = "4.2.0"

Then create a RNG like:

use rand_mt::Mt64;

let mut rng = Mt64::new_unseeded();
assert_ne!(rng.next_u64(), rng.next_u64());

Crate Features

rand_mt is no_std compatible. rand_mt has several optional features that are enabled by default:

rand-traits - Enables a dependency on rand_core. Activating this feature implements RngCore and SeedableRng on the RNGs in this crate.
std - Enables a dependency on the Rust Standard Library. Activating this feature enables std::error::Error impls on error types in this crate.

Mersenne Twister requires ~2.5KB of internal state. To make the RNGs implemented in this crate practical to embed in other structs, you may wish to store the RNG in a Box.

Minimum Supported Rust Version

This crate requires at least Rust 1.47.0. This version can be bumped in minor releases.
