Refactoring in Rust: Abstraction with the Newtype Pattern

This Rust tutorial demonstrates refactoring a brittle file name extraction process using the Newtype pattern. It shows how to create a `FileName` wrapper type to encapsulate the conversion logic from `PathBuf`, safely handle potential `None` values without `unwrap()`, and create a more robust and maintainable abstraction.
