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

Serde in action
Click to show Cargo.toml. Run this code in the playground.
[dependencies]
# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }
# 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"
use serde::{Serialize, Deserialize};
#[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.
