Module madsim::rand

Utilities for random number generation.

This module re-exports the rand crate, except for the random number generators.

User should call thread_rng() to retrieve the deterministic random number generator from the current madsim context. Do not use rand crate directly, because no determinism is guaranteed.

Example

use madsim::{runtime::Runtime, rand::{thread_rng, Rng}};

Runtime::new().block_on(async {
    let mut rng = thread_rng();
    rng.gen_bool(0.5);
    rng.gen_range(0..10);
});
