match - Rust By Example
Description: A description

# match

Rust provides pattern matching via the `match` keyword, which can be used like a C `switch`.

    fn main() {
        let number = 13;
        // TODO ^ Try different values for `number`

        println!("Tell me about {}", number);
        match number {
            // Match a single value
            1 => println!("One!"),
            // Match several values
            2 | 3 | 5 | 7 | 11 => println!("This is a prime"),
            // Match an inclusive range
            13...19 => println!("A teen"),
            // Handle the rest of cases
            _ => println!("Ain't special"),
        }

        let boolean = true;
        // Match is an expression too
        let binary = match boolean {
            // The arms of a match must cover all the possible values
            false => 0,
            true => 1,
            // TODO ^ Try commenting out one of these arms
        };

        println!("{} -> {}", boolean, binary);
    }
