Serde JSON   Build Status Latest Version

Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.

Serde JSON in action

[dependencies]
serde_json = "0.8"

Out of the box, Serde JSON is able to serialize and deserialize most Rust standard library types as JSON (primitives, String, HashMap, tuples, Vec, Option, etc). This works equally well on stable and nightly compilers and does not require code generation or a build script.

Serde JSON can also serialize and deserialize structs and enums defined in your program. See Serde's codegen documentation for how to set this up.

#[macro_use]
extern crate serde_derive;

extern crate serde_json;

#[derive(Serialize, Deserialize, Debug)]
struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };

    // Convert the Point to a JSON string.
    let serialized = serde_json::to_string(&point).unwrap();

    // Prints serialized = {"x":1,"y":2}
    println!("serialized = {}", serialized);

    // Convert the JSON string back to a Point.
    let deserialized: Point = serde_json::from_str(&serialized).unwrap();

    // Prints deserialized = Point { x: 1, y: 2 }
    println!("deserialized = {:?}", deserialized);
}

Getting help

Serde developers live in the #serde channel on irc.mozilla.org. The #rust channel is also a good resource with generally faster response time but less specific knowledge about Serde. If IRC is not your thing, we are happy to respond to GitHub issues as well.
