Refactoring in Rust: Introducing Traits

This Rust programming article demonstrates how to refactor code that extracts data from a HashMap of HTTP headers. It identifies problems with repetitive and unclear code for handling optional and required headers, and introduces a new 'Headers' type with dedicated methods (get_required_header, get_optional_header) to add semantics, improve safety by removing unwrap(), and clarify intent.
