YA-Rand: Yet Another Rand

Provides simple and fast pseudo/crypto random number generation.

It is highly recommend that you add RUSTFLAGS=--cfg windows_raw_dylib to your path. Currently, the getrandom crate that's used to seed RNGs behind the scenes defers it's operation to windows-targets, which by default links to a 5-12MB static lib. Adding the above cfg flag tells it to instead use the raw-dylib feature, which was stabilized in Rust 1.71. This turns windows-targets into a small macro-only library, which improves compile times and decreases binary size for both debug and release builds.

Usage

These are just a few simple examples to get you started.

use ya_rand::*;

// **Correct** instantiation is very easy.
// This seeds the RNG using operating system entropy,
// so you never have to worry about the quality of the
// initial state of RNG instances.
let mut rng = new_rng();

// Generate a random number with a given upper bound.
let max: u64 = 420;
let val = rng.bound(max);
assert!(val < max);

// Generate a random number in a given range.
let min: i64 = -69;
let max: i64 = 69;
let val = rng.range(min, max);
assert!(min <= val && val < max);

// Generate a random floating point value.
let val = rng.f64();
assert!(0.0 <= val && val < 1.0);

// Generate a random ascii digit: '0'..='9' as a char.
let digit = rng.ascii_digit();
assert!(digit.is_ascii_digit());
