Rhai - embedded scripting for Rust

Rhai is a tiny, simple and very fast embedded scripting language for Rust that gives you a safe and easy way to add scripting to your applications. It provides a familiar syntax based on JS and Rust and a simple Rust interface. Here is a quick example. First, the contents of my_script.rhai:

fn factorial(x) {
    if x == 1 { return 1; }
    x * factorial(x - 1)
}

compute_something(factorial(10))

And the Rust part:

use rhai::{Engine, RegisterFn};

fn compute_something(x: i64) -> bool {
    (x % 40) == 0
}

let mut engine = Engine::new();
engine.register_fn("compute_something", compute_something);
assert_eq!(engine.eval_file::<bool>("my_script.rhai"), Ok(true));
