rustYAML serde example in Rust

YAML is a popular data serialization format that is used to store data in a human-readable format. Rust provides a library called serde_yaml which can be used to serialize and deserialize YAML data.

Example code:

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

#[derive(Serialize, Deserialize)]
struct Person {
    name: String,
    age: u8,
}

fn main() {
    let person = Person {
        name: "John".to_string(),
        age: 30,
    };

    let serialized = serde_yaml::to_string(&person).unwrap();
    println!("Serialized: {}", serialized);

    let deserialized: Person = serde_yaml::from_str(&serialized).unwrap();
    println!("Deserialized: {:?}", deserialized);
}

Output example

Serialized: age: 30
name: John

Deserialized: Person { name: "John", age: 30 }

Code parts with detailed ## Explanation

• use serde::{Deserialize, Serialize};: This imports the Serialize and Deserialize traits from the serde crate. These traits are used to define the data structure that will be serialized and deserialized.
• #[derive(Serialize, Deserialize)]: This is a Rust macro that automatically implements the Serialize and Deserialize traits for the Person struct.
• serde_yaml::to_string(&person).unwrap(): This uses the serde_yaml crate to serialize the person struct into a YAML string.
• serde_yaml::from_str(&serialized).unwrap(): This uses the serde_yaml crate to deserialize the YAML string into a Person struct.
