Defining Structs and Creating Instances

Structs are custom data types that group related fields together. Here we define a User struct with three fields, then create an instance by specifying each field's value. Field access uses dot notation.

snippet.rs

rust

struct User {
    username: String,
    email: String,
    active: bool,
}
 
fn main() {
    let user1 = User {
        username: String::from("alice"),
        email: String::from("[email protected]"),
        active: true,
    };
    
    println!("User: {} ({})", user1.username, user1.email);
}

Defines a struct named User with three fields

username: String,

Field named username of type String

let user1 = User { ... };

Creates a new User instance with specific values
