serde_sono

A serde de-/serializer for the Sono data format.

Example

    use serde::Deserialize;

    #[derive(Deserialize, Debug)]
    struct Hobby(String);

    #[derive(Deserialize, Debug)]
    struct Person {
        name: String,
        age: u32,
        hobby: Hobby,
        #[serde(default)]
        friends: Vec<Person>,
    }

    fn main() {
        let input = r#"

Person {
    name: "katie",
    age: 10,
    hobby: "reading",
    friends: [
        { name: "tom", age: 33, hobby: "writing" },
        Person("bea", 9, Hobby("transpiling"), []),
        Person { name: "josh", hobby: "dreaming", age: 12 },
    ]
}

"#;
        match serde_sono::from_str::<Person>(input) {
            Err(e) => println!("syntax error: {e:#}"),
            Ok(value) => println!("{value:#?}"),
        }
    }

TODOs

• Pretty formatting when serializing
• Generic data model serde_sono::Value
• Efficient value skipping / ignoring
• Documentation
• Measure and tweak performance

Features

• value: enabled by default; guards the serde_sono::Value type

• lossless-serialize-value-leaking: Implements serde::Serialize for serde_sono::Value producing a lossless presentation of the serialized values at the cost of leaking memory for object names and property keys to support serializes which do retain references to these.

  The feature is disabled by default and results in objects being serialized as lists and/or maps of their properties.

  This feature is an alternative to lossless-serialize-value-unsafe.

• lossless-serialize-value-unsafe: Implements serde::Serialize for serde_sono::Value producing a lossless presentation of the serialized values by assuming that the used serializer does not retain references to the handed object and property names. (The serializer provided by serde_sono, for example, does not.)

  The feature is disabled by default and results in objects being serialized as lists and/or maps of their properties.

  This feature is an alternative to lossless-serialize-value-leaking.
