perchance 0.5.3

Very simple random number generation optimized for ease of use
Documentation

🎲 perchance

A lightweight, quick, and easy-to-use library for generating and using randomness, designed for the most common use cases you find in games and geometry.

Note that perchance is not cryptographically secure and should not be used in contexts where security is a concern.

Usage

perchance is a simple random number generation library, tuned for ease of use: create an instance of PerchanceContext and go.

let mut rng = perchance::PerchanceContext::new(seed);

let between_0_and_1 = rng.uniform_f32();
let dice_roll = rng.uniform_range_i32(1..=6);
let random_direction = rng.uniform_sphere_surface_vec3();
let thing_should_happen = rng.get_bool();

enum Event {
    Thing1,
    Thing2,
    Thing3,
}
let which_should_happen = rng.choose(&[Event::Thing1, Event::Thing2, Event::Thing3]);

You can also use the global perchance::global() if you have the std feature enabled:

// Seed the global context first. You may do so manually, or, on platforms that support it,
// obtain a seed to pass into it by calling `perchance::gen_time_seed()`.
perchance::seed_global(0x5F3759DF); // ;)

let mut rng = perchance::global();
let between_0_and_1 = rng.uniform_f32();
