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]: https://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].
[GitHub releases]: https://github.com/dtolnay/serde-yaml/releases
## Using Serde YAML
[API documentation is available in rustdoc form][docs.rs] but the general idea
is:
[docs.rs]: https://docs.rs/serde_yaml
```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: 1.0\ny: 2.0\n");
// 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: 1.0\ny: 2.0");
let deserialized_point: Point = serde_yaml::from_str(&s)?;
assert_eq!(point, deserialized_point);
Ok(())
}
```
