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

[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"





rust
use serde::{Deserialize, Serialize};

[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 is one of the most widely used Rust libraries so any place that Rustaceans
congregate will be able to help you out. For chat, consider trying the
[rust-questions] or [rust-beginners] channels of the unofficial community
Discord (invite: ), the [rust-usage] or
[beginners] channels of the official Rust Project Discord (invite:
), or the [general][zulip] stream in Zulip. For
asynchronous, consider the [\[rust\] tag on StackOverflow][stackoverflow], the
[/r/rust] subreddit which has a pinned weekly easy questions post, or the Rust
[Discourse forum][discourse]. It's acceptable to file a support issue in this
repo but they tend not to get as many eyes as any of the above and may get
closed without a response after some time.
