//! # 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`:
//!
//! ```rust,ignore
//! fn factorial(x) {
//!     if x == 1 { return 1; }
//!	    x * factorial(x - 1)
//! }
//!
//! compute_something(factorial(10))
//! ```
//!
//! And the Rust part:
//!
//! ```rust,no_run
//! 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));
//! ```
//!
//! [Check out the README on GitHub for more information!](https://github.com/jonathandturner/rhai)
