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.

## 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(())
|
|
}
|
|
```
