Use the serde crate to convert JSON strings into Rust structs and back for handling web requests and responses.

Use the serde crate to deserialize JSON request bodies into structs and serialize structs into JSON responses.

use serde::{Deserialize, Serialize};
use serde_json;

#[derive(Deserialize, Serialize)]
struct Data { id: u32, name: String }

// Deserialize request
let json = r#"{"id": 1, "name": "test"}"#;
let data: Data = serde_json::from_str(json).unwrap();

// Serialize response
let response = serde_json::to_string(&data).unwrap();
