This crate is a Rust library for using the [Serde] serialization framework with
data in [YAML] file format.

[Serde]: https://github.com/serde-rs/serde
[YAML]: http://yaml.org

This library does not reimplement a YAML parser; it uses [yaml-rust] which is a
pure Rust YAML 1.2 implementation.

[yaml-rust]: https://github.com/chyh1990/yaml-rust

## Dependency

```toml
[dependencies]
serde = "1.0"
serde_yaml = "0.8"
```

Release notes are available under [GitHub releases].

## Using Serde YAML

[API documentation is available in rustdoc form][docs.rs] but the general idea
is:

```rust
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 s = serde_yaml::to_string(&map)?;
    assert_eq!(s, "---\nx: 1\ny: 2");

    // Deserialize it back to a Rust type.
    let deserialized_map: BTreeMap<String, f64> = serde_yaml::from_str(&s)?;
    assert_eq!(map, deserialized_map);
    Ok(())
}
```

It can also be used with Serde's derive macros to handle structs and enums
defined by your program.

```toml
[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_yaml = "0.8"
```

```rust
use serde::{Serialize, Deserialize};

#[derive(Debug, PartialEq, Serialize, Deserialize)]
struct Point {
    x: f64,
    y: f64,
}

fn main() -> Result<(), serde_yaml::Error> {
    let point = Point { x: 1.0, y: 2.0 };

    let s = serde_yaml::to_string(&point)?;
    assert_eq!(s, "---\nx: 1\ny: 2");

    let deserialized_point: Point = serde_yaml::from_str(&s)?;
    assert_eq!(point, deserialized_point);
    Ok(())
}
```
