What are some examples of serialization in Rust?

In Rust, serialization is often done using libraries like Serde. For example, you can serialize a struct to JSON.

Can you show me a code example of serializing a struct?

Sure! Here's a simple example:

use serde::{Serialize, Deserialize};

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

fn main() {
    let person = Person { name: String::from("Alice"), age: 30 };
    let json = serde_json::to_string(&person).unwrap();
    println!("Serialized: {}", json);
}

What about deserialization? How does that work?

Deserialization is the reverse process. You can convert JSON back into a Rust struct using serde_json::from_str. Here's an example:

let json_data = r#"{"name":"Alice","age":30}"#;
let person: Person = serde_json::from_str(json_data).unwrap();
println!("Deserialized: {:?}", person);
