Tuples

This section describes how to use tuples to store multiple types in one variable.

Foundations

A tuple is an anonymous struct containing values of one or more different types.

Creating a tuple uses the signature: tuple<type, [type], [type…]> variable_name;

A tuple starts with all memory zero initialized and can be filled using an initializer list [ ] expression or by writing to number indexes corresponding to the types in the definition signature.

    // make an empty tuple that can hold an i32, f32, and string
    tuple<i32,f32,string> t;
    println(t[0] as string + ", " + t[1] as string + ", " + t[2]); // 0, 0.000000,

    // same thing, but fill with values
    tuple<i32,f32,string> t = [ 1, 2.5, "test" ];
    println(t[0] as string + ", " + t[1] as string + ", " + t[2]); // 1, 2.500000, test

    // assignment to index
    t[0] = 3;
    t[1] = 4.5;
    t[2] = "foo";
    println(t[0] as string + ", " + t[1] as string + ", " + t[2]); // 3, 4.500000, foo
