Rust by Example

Tuples can be destructured in a match as follows:

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"),

// `..` can be the used ignore the rest of the tuple

_      => println!("It doesn't matter what they are"),

// `_` means don't bind the value to a variable

}

}
