Tuples

A tuple collects multiple values like an array, but with the added ability to collect values of different types:

fn main() {
    let tup: (u8, u64, Field) = (255, 500, 1000);
}

One way to access tuple elements is via destructuring using pattern matching:

fn main() {
    let tup = (1, 2);

    let (one, two) = tup;

    let three = one + two;
}

Another way to access tuple elements is via direct member access, using a period (.) followed by the index of the element we want to access. Index 0 corresponds to the first tuple element, 1 to the second and so on:

fn main() {
    let tup = (5, 6, 7, 8);

    let five = tup.0;
    let eight = tup.3;
}
