[Rust Guide] 7.3. Path Pt. 2 - Accessing Parent Modules and Pub on Structs and Enums

To keep learning along, follow this series. 7.3.1 super We can access items in a parent module’s path by using super at the start of a path, just like using .. syntax to start a file-system path. For example: fn deliver_order () {} mod back_of_house { fn fix_incorrect_order () { cook_order (); super :: deliver_order (); } fn cook_order () {} } Of course, you can use an absolute path to achieve the same result: fn deliver_order () {} mod back_of_house { fn fix_incorrect_order () { cook_order (); crate :: deliver_order (); } fn cook_order () {} } 7.3.2 pub struct If you put the pub keyword before struct , the struct becomes public, as shown below: mod back_of_house { pub struct Breakfast { toast : String , seasonal_fruit : String , } } Note that although this struct is public, the fields inside a struct are private by default , unless you add the pub keyword. In Rust, in most cases if something does not have pub , then it is pr
