Beginner

Code

struct User {
    name: String,
    age: u32,
    email: String,
}

fn main() {
    let user = User {
        name: String::from("Alice"),
        age: 30,
        email: String::from("alice@example.com"),
    };
    println!("{} is {} years old", user.name, user.age);
}

Explanation

Structs group related data. Fields are accessed with dot notation. String::from creates owned strings.
