Define enum variants with tuple or struct syntax and extract their data using pattern matching in a match expression.

Define data inside enum variants using tuple or struct syntax, then access it via pattern matching with match.

enum Message {
    Quit,
    Move { x: i32, y: i32 },
    Write(String),
    ChangeColor(u8, u8, u8),
}

fn main() {
    let msg = Message::Write(String::from("hello"));
    match msg {
        Message::Write(text) => println!("Text message: {}", text),
        Message::Move { x, y } => println!("Move to ({}, {})", x, y),
        Message::ChangeColor(r, g, b) => println!("Change color to ({}, {}, {})", r, g, b),
        Message::Quit => println!("Quit"),
    }
}
