Day 13k: Serialization and Deserialization of Vectors

Introduction

Serialization and deserialization are important when working with data formats like JSON. Rust’s serde library allows you to easily serialize and deserialize vectors. In this session, we’ll cover how to convert vectors to and from JSON.

Serializing a Vector to JSON

To serialize a vector into JSON, you can use the serde_json crate. Here’s an example:

use serde_json::json;



fn main() {

    let numbers = vec![1, 2, 3, 4, 5];

    let json = serde_json::to_string(&numbers).unwrap();

    println!("{}", json);  // Output: [1,2,3,4,5]

}

Deserializing JSON to a Vector

To deserialize JSON back into a vector, use serde_json::from_str():

use serde_json::json;



fn main() {

    let data = "[1, 2, 3, 4, 5]";

    let numbers: Vec<i32> = serde_json::from_str(data).unwrap();

    println!("{:?}", numbers);  // Output: [1, 2, 3, 4, 5]

}

Conclusion

Serialization and deserialization allow you to convert vectors into formats like JSON for storage or transmission. With the help of the serde library, these conversions become straightforward.
