The author demonstrates a practical Rust technique of decomposing the std::path::Component enum into separate, strongly-typed structs for each variant (e.g., NormalComponent), improving compile-time guarantees and API expressiveness when working with file paths.
Background
Rust's type system encourages precise, expressive interfaces; this technique applies the principle of representing distinct cases as distinct types rather than using broad enums or generic strings.
