Rust

//! The Dust programming language.
//!
//! To get started, you can use the `run` function to run a Dust program.
//!
//! ```rust
//! use dust_lang::{run, Value};
//!
//! let program = "
//! let foo = 21
//! let bar = 2
//! foo * bar
//! ";
//!
//! let the_answer = run(program).unwrap();
//!
//! assert_eq!(the_answer, Some(Value::integer(42)));
//! ```
