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