Click to show Cargo.toml. Run this code in the playground. ```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::{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.
