tuples

Tuples can be destructured in a match as follows:

  1. fn main() {
  2.     let pair = (0, -2);
  3.     // TODO ^ Try different values for `pair`
  5.     println!("Tell me about {:?}", pair);
  6.     // Match can be used to destructure a tuple
  7.     match pair {
  8.         // Destructure the second
  9.         (0, y) => println!("First is `0` and `y` is `{:?}`", y),
  10.         (x, 0) => println!("`x` is `{:?}` and last is `0`", x),
  11.         _      => println!("It doesn't matter what they are"),
  12.         // `_` means don't bind the value to a variable
  13.     }
  14. }
