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.

This crate provides a convenient concise way to write unit tests for //! implementations of [`Serialize`] and [`Deserialize`]. //! //! [`Serialize`]: serde::ser::Serialize //! [`Deserialize`]: serde::de::Deserialize //! //! The `Serialize` impl for a value can be characterized by the sequence of //! [`Serializer`] calls that are made in the course of serializing the value, //! so `serde_test` provides a [`Token`] abstraction which corresponds roughly //! to `Serializer` method calls. There is an [`assert_ser_tokens`] function to //! test that a value serializes to a particular sequence of method calls, an //! [`assert_de_tokens`] function to test that a value can be deserialized from //! a particular sequence of method calls, and an [`assert_tokens`] function to //! test both directions. There are also functions to test expected failure //! conditions. //! //! [`Serializer`]: serde::ser::Serializer //! //! Here is an example from the [`linked-hash-map`] crate. //! //!
