Serde Norway, a Serde YAML fork :)
==========

A hard-fork of Serde YAML. I'm not committing to maintaining this long-term
(yet). However, I also need it, because I'm in a platform team :)
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/
</div>
## Dependency
```toml
[dependencies]
serde = "1.0"
serde_norway = "0.9"
```
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_norway
```rust
use std::collections::BTreeMap;
fn main() -> Result<(), serde_norway::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 yaml = serde_norway::to_string(&map)?;
assert_eq!(yaml, "x: 1.0\ny: 2.0\n");
// Deserialize it back to a Rust type.
let deserialized_map: BTreeMap<String, f64> = serde_norway::from_str(&yaml)?;
assert_eq!(map, deserialized_map);
Ok(())
}
```
It can also be used with Serde's derive macros to handle structs and enums
defined in your program.
```toml
[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_norway = "0.9"
```
Structs serialize in the obvious way:
```rust
use serde::{Serialize, Deserialize};
#[derive(Debug, PartialEq, Serialize, Deserialize)]
struct Point {
x: f64,
y: f64,
}
fn main() -> Result<(), serde_norway::Error> {
let point = Point { x: 1.0, y: 2.0 };
let yaml = serde_norway::to_string(&point)?;
assert_eq!(yaml, "x: 1.0\ny: 2.0\n");
let deserialized_point: Point = serde_norway::from_str(&yaml)?;
assert_eq!(point, deserialized_point);
Ok(())
}
```
Enums serialize using YAML's `!tag` syntax to identify the variant name.
```rust
use serde::{Serialize, Deserialize};
#[derive(Serialize, Deserialize, PartialEq, Debug)]
enum Enum {
Unit,
Newtype(usize),
Tuple(usize, usize, usize),
Struct { x: f64, y: f64 },
}
fn main() -> Result<(), serde_norway::Error> {
let yaml = "
- !Newtype 1
- !Tuple [0, 0, 0]
- !Struct {x: 1.0, y: 2.0}
";
let values: Vec<Enum> = serde_norway::from_str(yaml).unwrap();
assert_eq!(values[0], Enum::Newtype(1));
assert_eq!(values[1], Enum::Tuple(0, 0, 0));
assert_eq!(values[2], Enum::Struct { x: 1.0, y: 2.0 });
// The last two in YAML's block style instead:
let yaml = "
- !Tuple
- 0
- 0
- 0
- !Struct
x: 1.0
y: 2.0
";
let values: Vec<Enum> = serde_norway::from_str(yaml).unwrap();
assert_eq!(values[0], Enum::Tuple(0, 0, 0));
assert_eq!(values[1], Enum::Struct { x: 1.0, y: 2.0 });
// Variants with no data can be written using !Tag or just the string name.
let yaml = "
- Unit # serialization produces this one
- !Unit
";
let values: Vec<Enum> = serde_norway::from_str(yaml).unwrap();
assert_eq!(values[0], Enum::Unit);
assert_eq!(values[1], Enum::Unit);
Ok(())
}
