This book is for Rust developers who are comfortable with the language and now want to improve their coding abilities by learning advanced functional techniques to enhance their skillset and create robust and testable apps.

The primary benefits of declarative style over imperative style are that declarative style is self-documenting and prevents mistakes by making them more obvious.
