Compound Types

    Tuple assignment and access:

    1. fn main() {
    3.     println!("1st index: {}", t.0);
    4.     println!("2nd index: {}", t.1);

    Key points:

    Arrays:

    • We can use literals to assign values to arrays.

    • In the main function, the print statement asks for the debug implementation with the ? format parameter: {} gives the default output, gives the debug output. We could also have used {a} and {a:?} without specifying the value after the format string.

    • Adding #, eg {a:#?}, invokes a “pretty printing” format, which can be easier to read.

    • Tuples group together values of different types into a compound type.

    • Fields of a tuple can be accessed by the period and the index of the value, e.g. t.0, t.1.

      • You can think of it as void that can be familiar to you from other programming languages.
