#[derive(Serialize)]
struct Person {
    name: String,
    age: u16,
    languages: Vec<String>,
}

fn main() {
    let person = Person {
        name: "JiangBo".to_owned(),
        age: 44,
        languages: vec!["Rust".to_owned(), "Java".to_owned()],
    };

    let json = serde_json::to_string(&person).unwrap();
    println!("{}", json);
}

Cargo.toml

[package]
edition = "2021"
name = "game"
version = "0.1.0"
