//! This crate allows you to serialize and deserialize any type that implements
//! `serde::Serialize` and `serde::Deserialize` into/from `rlua::Value`.
//!
//! Implementation is similar to `serde_json::Value`
//!
//! Example usage:
//!
//! ```rust
//! extern crate serde;
//! #[macro_use]
//! extern crate serde_derive;
//! extern crate rlua;
//! extern crate rlua_serde;
//!
//! fn main() {
//!     #[derive(Serialize, Deserialize)]
//!     struct Foo {
//!         bar: u32,
//!         baz: Vec<String>,
//!     }
//!
//!     let lua = rlua::Lua::new();
//!     lua.context(|lua| {
//!         let foo = Foo {
//!             bar: 42,
//!             baz: vec![String::from("fizz"), String::from("buzz")],
//!         };
//!
//!         let value = rlua_serde::to_value(lua, &foo).unwrap();
//!         lua.globals().set("value", value).unwrap();
//!         lua.load(
//!             r#"
//!                 assert(value["bar"] == 42)
//!                 assert(value["baz"][2] == "buzz")
//!             "#).exec().unwrap();
//!     });
//! }
//! ```
