## Serde in action
|
|
|
|
```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: <https://discord.gg/rust-lang-community>, the [#rust-usage] or
|
|
[#beginners] channels of the official Rust Project Discord (invite:
|
|
<https://discord.gg/rust-lang>), 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.
