[dependencies]

# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde.
serde = "1.0"

# Support for #[derive(Serialize, Deserialize)]. Required if you want Serde
# to work for structs and enums defined in your crate.
serde_derive = "1.0"

# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"

#[macro_use]
extern crate serde_derive;

extern crate serde;
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 or you don't get a good response, we are happy to respond to GitHub issues as well.
