//! This crate is a Rust library for using the [Serde] serialization framework
//! with data in [YAML] file format.
//!
//! This library does not reimplement a YAML parser; it uses [yaml-rust] which
//! is a pure Rust YAML 1.2 implementation.
//!
//! [Serde]: https://github.com/serde-rs/serde
//! [YAML]: http://yaml.org
//! [yaml-rust]: https://github.com/chyh1990/yaml-rust
//!
//! # Examples
//!
//! ```rust
//! extern crate serde_yaml;
//!
//! use std::collections::BTreeMap;
//!
//! // You have some type.
//! let mut map = BTreeMap::new();
//! map.insert("x".to_string(), 1.0);
//! map.insert("y".to_string(), 2.0);
//!
//! // Serialize it to a YAML string.
//! let s = serde_yaml::to_string(&map).unwrap();
//! assert_eq!(s, "---\nx: 1.0\ny: 2.0");
//!
//! // Deserialize it back to a Rust type.
//! let deserialized_map: BTreeMap<String, f64> = serde_yaml::from_str(&s).unwrap();
//! assert_eq!(map, deserialized_map);
//! ```
//!
//! ## Using serde derive
//!
//! It can also be used with Serde's serialization code generator `serde_derive` to
//! handle structs and enums defined in your own program.
//!
//! ```rust
//! #[macro_use] extern crate serde_derive;
//! extern crate serde_yaml;
//!
//! #[derive(Debug, PartialEq, Serialize, Deserialize)]
//! struct Point { x: f64, y: f64 }
//!
//! # fn main() {
//! let point = Point { x: 1.0, y: 2.0 };
//!
//! let s = serde_yaml::to_string(&point).unwrap();
//! assert_eq!(s, "---\nx: 1.0\ny: 2.0");
//!
//! let deserialized_point: Point = serde_yaml::from_str(&s).unwrap();
//! assert_eq!(point, deserialized_point);
//! # }
//! ```
//!
//! ## 128 bit numbers
//!
//! Support for `i128` and `u128` on Rust toolchains after `1.26.0` is enabled
//! through the `i128` feature.  Add the following to `Cargo.toml`:
//!
//! ```toml,ignore
//! [dependencies.serde-yaml]
//! features = ["i128"]
//! ```
