Rust implementation for TinyMT 64/32 -- Mersenne Twister PRNGs with Lightweight Footprint. This repository is based on the original TinyMT 1.1.1 @ 9d7ca3c161 implemented in C.
You would use TinyMT random numbers by simply adding the URL of this repository to your project's Cargo.toml.
toml
[dependencies]
rand = "0.7"
tinymt = "1.0"
In the head of your source, please declare the tinymt crate, and then retrieve random numbers using TinyMT64 or
its 32-bit edition, TinyMT32.
```rust extern crate tinymt;
use rand::{Rng, SeedableRng}; use tinymt::{TinyMT64, TinyMT64Seed};
fn main() { // from nondeterministic seed let mut random = TinyMT64::fromentropy(); let rn = random.genrange(0.0, 1.0); println!("{}", rn); // => nondeterministic but such that 0.3487526381670172
// from deterministic seed (reproduction of random number sequence is possible) let mut random = TinyMT64::fromseed(TinyMT64Seed::from(0u64)); let rn = random.genrange(0.0, 1.0); println!("{}", rn); // => 0.5531250908497853 } ```
The TinyMT64 and TinyMT32 respectively implement the rand::RngCore features that is widely-used PRNG interface in
Rust.
The modules tinymt::tinymt64 and tinymt::tinymt32 that have been migrated from the original C implementation are
independent of external libraries. This allows you to use them if you expect exactly the same behavior as the original
C implementation, of if there are some conflicts between the versions of rand that TinyMT depends on.
See the API Reference for all functions.
The followings are typical cargo commands used to test, verify the quality of TinyMT.
$ cargo +nightly test
$ cargo +nightly clippy
$ cargo +nightly fmt # or fmt -- --check
