## Serde in action

Click to show Cargo.toml.
Run this code in the playground. (https://play.rust-lang.org/?edition=2018&gist=72755f28f99afc95e01d63174b28c1f5)

```toml
[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::{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`][irc]. 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][issues] as well.
