This article discusses tuples in the Cairo compiler version 2.0.0-rc0. Tuples are a type that allows for combining multiple different types into a collection. Once declared, the number and types of elements in a tuple cannot be changed. The code example demonstrates creating a tuple and extracting its elements.

Tuple in Cairo#

The version of the Cairo compiler used in this article is 2.0.0-rc0. Since Cairo is being updated rapidly, the syntax may vary slightly in different versions, and the content of the article will be updated to a stable version in the future.

A tuple is an interesting type that is present in many programming languages. It allows different types to be combined together to form a collection. Once declared, the number of types it can hold cannot be increased or decreased, and the types inside it cannot be changed.

Basic Usage#

use debug::PrintTrait;

fn main() {
    let tup: (u32, u64, bool) = (10, 20, true);
    let (x, y, z) = tup;
    x.print();
}

In the above code, a tuple is created that contains three types: u32, u64, bool. The line let (x, y, z) = tup; demonstrates how the elements of the tuple can be extracted.
