Rust Pattern Matching with match

fn classify(n: i32) -> &'static str {
    match n {
        0 => "zero",
        1 | 2 | 3 => "small",
        4..=9 => "medium",
        n if n < 0 => "negative",
        _ => "large",
    }
}

fn main() {
    for n in [0, 2, 7, -5, 42] {
        println!("{n}: {}", classify(n));
    }

    let point = (0, 8);
    match point {
        (0, y) => println!("on the y axis at {y}"),
        (x, 0) => println!("on the x axis at {x}"),
        (x, y) => println!("at ({x}, {y})"),
    }

    let maybe = Some(3);
    if let Some(value) = maybe {
        println!("got {value}");
    }
}
