Paths

path can take two forms:

• An absolute path is the full path starting from a crate root; for code from an external crate, the absolute path begins with the crate name, and for code from the current crate, it starts with the literal crate.
• A relative path starts from the current module and uses self, super, or an identifier in the current module.

mod front_of_house {    mod hosting {        fn add_to_waitlist() {}    }}pub fn eat_at_restaurant() {    // Absolute path    crate::front_of_house::hosting::add_to_waitlist();    // Relative path    front_of_house::hosting::add_to_waitlist();}
