| # tuples |
| |
| Tuples can be destructured in a `match` as follows: |
| |
| ```rust,editable |
| fn main() { |
| let triple = (0, -2, 3); |
| // TODO ^ Try different values for `triple` |
| |
| println!("Tell me about {:?}", triple); |
| // Match can be used to destructure a tuple |
| match triple { |
| // Destructure the second and third elements |
| (0, y, z) => println!("First is `0`, `y` is {:?}, and `z` is {:?}", y, z), |
| (1, ..) => println!("First is `1` and the rest doesn't matter"), |
| (.., 2) => println!("last is `2` and the rest doesn't matter"), |
| (3, .., 4) => println!("First is `3`, last is `4`, and the rest doesn't matter"), |
| // `..` can be used to ignore the rest of the tuple |
| _ => println!("It doesn't matter what they are"), |
| // `_` means don't bind the value to a variable |
| } |
| } |
| ``` |
