Having to write out the paths to call functions can feel inconvenient and repetitive. In Listing 7-7, whether we chose the absolute or relative path to the add_to_waitlist function, every time we wanted to call add_to_waitlist we had to specify front_of_house and hosting too. Fortunately, there’s a way to simplify this process: we can create a shortcut to a path with the use keyword once, and then use the shorter name everywhere else in the scope. In Listing 7-11, we bring the crate::front_of_house::hosting module into the scope of the eat_at_restaurant function so we only have to specify hosting::add_to_waitlist to call the add_to_waitlist function in eat_at_restaurant. Filename: src/lib.rs Listing 7-11: Bringing a module into scope with use Adding use and a path in a scope is similar to creating a symbolic link in the filesystem. By adding use crate::front_of_house::hosting in the crate root, hosting is now a valid name in that scope, just as though the hosting module had been define
