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.
Version 0.5.* of serde_yaml
works with 0.8.* of Serde.
[dependencies]
serde_yaml = "0.5"
Release notes are available under GitHub releases.
API documentation is available in rustdoc form but the general idea is:
extern crate serde_yaml;
use std::collections::BTreeMap;
fn main() {
// 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\ny: 2");
// Deserialize it back to a Rust type.
let deserialized_map: BTreeMap<String, f64> = serde_yaml::from_str(&s).unwrap();
assert_eq!(map, deserialized_map);
}
It can also be used with Serde's serialization code generator serde_derive
to
handle structs and enums defined in your own program.

struct Point {

let deserialized_point: Point = serde_yaml::from_str(&s).unwrap();
