When you want to work with the 'alternate screen' you can call the following functions: terminal::from_screen etc. Which will give you an instance to the back of the module you are calling it in. So instead of: let color = color(Screen::default()); let cursor = cursor(Screen::default()); let input = input(Screen::default()); let terminal = terminal(Screen::default()); You can do: let color = color(); let cursor = cursor(); let input = input(); let terminal = terminal();
