Error

The "unresolved import" error occurs because the item you are trying to use is private or not defined in the current scope. Add a use statement to bring the item into scope, ensuring the path is correct and the item is public.

use crate::back_of_house::fix_incorrect_order;

fn main() {
    // Now fix_incorrect_order is accessible
}

If the item is in a module, ensure it is marked pub in its definition, like pub fn fix_incorrect_order() {}.

The "unresolved import" error means your code is trying to use a piece of code that it cannot see. Think of it like trying to open a locked door; you need the right key (a use statement) or the door needs to be unlocked (marked as pub). You fix it by explicitly telling Rust where to find the code or making the code visible to the rest of your project.
