quad-rand

quad-rand 实现了基于 rust 原子的伪随机生成器 http://www.pcg-random.org/download.html

兼容 wasm 以及任何具有 std 的 rust 目标

基本用法，不涉及任何依赖

use quad_rand as qrand;

// seed random
qrand::srand(12345);

// get random number from 0 to u32::MAX
let x = qrand::rand();

// get random number from given range
let x = qrand::gen_range(0., 1.);
assert!(x >= 0. && x < 1.);

// gen_range works for most of standart number types
let x: u8 = qrand::gen_range(64, 128);
assert!(x >= 64 && x < 128);

可选的与 rand 仓库的兼容层

use quad_rand::compat::QuadRand;
use rand::seq::SliceRandom;

let mut vec = vec![1, 2, 3, 4, 5, 6];

// QuadRand is rand::RngCore implementation, allowing to use all the cool stuff from rand
vec.shuffle(&mut QuadRand);
