Hands-On Functional Programming in Rust

By: Andrew Johnson

Overview of this book

Functional programming allows developers to divide programs into smaller, reusable components that ease the creation, testing, and maintenance of software as a whole. Combined with the power of Rust, you can develop robust and scalable applications that fulfill modern day software requirements. This book will help you discover all the Rust features that can be used to build software in a functional way. We begin with a brief comparison of the functional and object-oriented approach to different problems and patterns. We then quickly look at the patterns of control flow, data the abstractions of these unique to functional programming. The next part covers how to create functional apps in Rust; mutability and ownership, which are exclusive to Rust, are also discussed. Pure functions are examined next and you'll master closures, their various types, and currying. We also look at implementing concurrency through functional design principles and metaprogramming using macros. Finally, we look at best practices for debugging and optimization. By the end of the book, you will be familiar with the functional approach of programming and will be able to use these techniques on a daily basis.

Summary

In this chapter, we introduced many applied and practical considerations for Rust programming. Performance and debugging are certainly not problems that are exclusive to Functional Programming. Here we tried to introduce tips that are generally applicable but also highly compatible with functional programming.

Metaprogramming in Rust may be considered a functional feature by itself. Logic programming and thereby derived functionality are closely associated with functional programming principles. The recursive, context-free nature of macros also lends itself to a functional perspective.

This is also the last chapter in the book. We hope you have enjoyed the book and we welcome any feedback. If you are looking for further reading, you might want to research some of the topics presented in the final three chapters of the book. There is an enormous amount of material available...
