Tuple Primitives

Tuple types และ operations

Creating Tuples

fn main() {
    // Basic tuple
    let pair = (42, "hello");
    println!("Pair: {:?}", pair);

    // With type annotation
    let typed: (i32, f64, bool) = (10, 3.14, true);
    println!("Typed: {:?}", typed);

    // Single element (note trailing comma)
    let single: (i32,) = (42,);
    println!("Single: {:?}", single);

    // Unit tuple
    let unit: () = ();
    println!("Unit: {:?}", unit);

    // Nested tuples
    let nested = ((1, 2), (3, 4));
    println!("Nested: {:?}", nested);

    // Large tuple (up to 12 for common traits)
    let big = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12);
    println!("Big: {:?}", big);

    // Mixed types
    let mixed = (42, "hello", true, 3.14, vec![1, 2, 3]);
    println!("Mixed: {:?}", mixed);
}
