This isn't a direct answer to your questions, because it doesn't actually explain how to mount the sub-modules into your crate (with mod) and how to expose functions to other modules (with pub), but that is (IMO) sufficiently explained in the book. That approach isn't idiomatic Rust and I would advise against its use without a good explanation of what it accomplishes. you can write File::options().append(true).open("example.log").
