//!
//! Rust library for using the [Serde] serialization framework with data in
//! [YAML] file format. _(This project is no longer maintained.)_
//!
//! [Serde]: https://github.com/serde-rs/serde
//! [YAML]: https://yaml.org/
//!
//! # Examples
//!
//! ```
//! use std::collections::BTreeMap;
//!
//! fn main() -> Result<(), serde_yaml::Error> {
//!     // 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 yaml = serde_yaml::to_string(&map)?;
//!     assert_eq!(yaml, "x: 1.0\ny: 2.0\n");
//!
//!     // Deserialize it back to a Rust type.
//!     let deserialized_map: BTreeMap<String, f64> = serde_yaml::from_str(&yaml)?;
//!     assert_eq!(map, deserialized_map);
//!     Ok(())
//! }
//! ```
//!
//! ## Using Serde derive
//!
//! It can also be used with Serde's derive macros to handle structs and enums
//! defined in your program.
//!
//! Structs serialize in the obvious way:
//!
//! ```
//! # use serde_derive::{Serialize, Deserialize};
//! use serde::{Serialize, Deserialize};
//!
//! #[derive(Serialize, Deserialize, PartialEq, Debug)]
//! struct Point {
//!     x: f64,
//!     y: f64,
//! }
//!
//! fn main() -> Result<(), serde_yaml::Error> {
//!     let point = Point { x: 1.0, y: 2.0 };
//!
//!     let yaml = serde_yaml::to_string(&point)?;
//!     assert_eq!(yaml, "x: 1.0\ny: 2.0\n");
//!
//!     let deserialized_point: Point = serde_yaml::from_str(&yaml)?;
//!     assert_eq!(point, deserialized_point);
//!     Ok(())
//! }
//! ```
//!
//! Enums serialize using YAML's `!tag` syntax to identify the variant name.
//!
//! ```
//! # use serde_derive::{Serialize, Deserialize};
//! use serde::{Serialize, Deserialize};
//!
//! #[derive(Serialize, Deserialize, PartialEq, Debug)]
//! enum Enum {
//!     Unit,
//!     Newtype(usize),
//!     Tuple(usize, usize, usize),
//!     Struct { x: f64, y: f64 },
//! }
//!
//! fn main() -> Result<(), serde_yaml::Error> {
//!     let yaml = "
//!         - !Newtype 1
//!         - !Tuple [0, 0, 0]
//!         - !Struct {x: 1.0, y: 2.0}
//!     ";
//!     let values: Vec<Enum> = serde_yaml::from_str(yaml).unwrap();
//!     assert_eq!(values[0], Enum::Newtype(1));
//!     assert_eq!(values[1], Enum::Tuple(0, 0, 0));
//!     assert_eq!(values[2], Enum::Struct { x: 1.0, y: 2.0 });
//!
//!     // The last two in YAML's block style instead:
//!     let yaml = "
//!         - !Tuple
//!           - 0
//!           - 0
//!           - 0
//!         - !Struct
//!           x: 1.0
//!           y: 2.0
//!     ";
//!     let values: Vec<Enum> = serde_yaml::from_str(yaml).unwrap();
//!     assert_eq!(values[0], Enum::Tuple(0, 0, 0));
//!     assert_eq!(values[1], Enum::Struct { x: 1.0, y: 2.0 });
//!
//!     // Variants with no data can be written using !Tag or just the string name.
//!     let yaml = "
//!         - Unit  # serialization produces this one
//!         - !Unit
//!     ";
//!     let values: Vec<Enum> = serde_yaml::from_str(yaml).unwrap();
//!     assert_eq!(values[0], Enum::Unit);
//!     assert_eq!(values[1], Enum::Unit);
//!
//!     Ok(())
//! }
//! ```
