Exercise - Visibility

  • 6 minutes

Unless explicitly noted, every item in a module is private. Only the public items of a module can be accessed from outside the module scope.

The following code has a compiler error. Your assignment in this exercise is to make the code compile successfully without modifying the main function.

mod car_factory {
    fn build_car() {
        println!("Honk honk!");
    }
}

fn main() {
    car_factory::build_car();
}

Hint: The compiler error should point to the item that needs to be public.
