Combinators

This chapter explores the use of combinators in Rust as elegant tools for transforming and managing data without explicit control flow. It begins by studying combinators on the Option type, showing how they help handle optional values concisely and safely. The discussion then extends to chaining combinators on Option, showing how multiple operations can be composed for clear and expressive code. The chapter further examine techniques for iterating over Option, bridging the gap between optional values and iterator-based processing.
