//! # High-level bindings to Lua
//!
//! The `rlua` crate provides safe high-level bindings to the [Lua programming language].
//!
//! # The `Lua` object
//!
//! The main type exported by this library is the [`Lua`] struct. In addition to methods for
//! [executing] Lua chunks or [evaluating] Lua expressions, it provides methods for creating Lua
//! values and accessing the table of [globals].
//!
//! # Converting data
//!
//! The [`ToLua`] and [`FromLua`] traits allow conversion from Rust types to Lua values and vice
//! versa. They are implemented for many data structures found in Rust's standard library.
//!
//! For more general conversions, the [`ToLuaMulti`] and [`FromLuaMulti`] traits allow converting
//! between Rust types and *any number* of Lua values.
//!
//! Most code in `rlua` is generic over implementors of those traits, so in most places the normal
//! Rust data structures are accepted without having to write any boilerplate.
//!
//! # Custom Userdata
//!
//! The [`UserData`] trait can be implemented by user-defined types to make them available to Lua.
//! Methods and operators to be used from Lua can be added using the [`UserDataMethods`] API.
