Rust/Variable/Type/Compound/Tuple

• can use Programming/Destructuring
• can access elements with dot notation, e.g. my_tuple.1 accesses the 2nd element in the Programming/Zero Indexing array
• Example
  • rust

    let my_tuple = (1, 2.0, 'a');
    let (a, b, c) = my_tuple;
    println!("Tuple elements: {a}, {b}, {c}");
    // Tuple elements: 1, 2, a
    let two_point_zero = my_tuple.1;
    println!("Accessed second element: {two_point_zero}");
    // Accessed second element: 2

• The tuple without any values is Rust/unit. This value and its corresponding type are both written () and represent an empty value or an empty return type. Expressions implicitly return the unit value if they don’t return any other value.
• Variables can use Rust/mut with Rust/Variable/let to make mutable tuples.
  • Example
    • rust

      fn test_tuple_mutation() {
          let mut x: (i32, i32) = (1, 2);
          x.0 = 0;
          x.1 += 5;
      }
