# match
Rust provides pattern matching via the `match` keyword, which can be used like
a C `switch`. The first matching arm is evaluated and all possible values must be
covered.
```rust,editable
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"),
// TODO ^ Try adding 13 to the list of prime values
// Match an inclusive range
13..=19 => println!("A teen"),
// Handle the rest of cases
_ => println!("Ain't special"),
// TODO ^ Try commenting out this catch-all arm
}
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);
}
```
