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.

Generics and Polymorphism

  1. What is an algebraic data type?

An algebraic data type is a kind of composite type formed by combining other types.

  1. What is polymorphism?

Polymorphism is the quality of having many forms.

  1. What is parametric polymorphism?

Parametric polymorphism is the quality of having many forms according to a parameter.

  1. What is a ground type?

A ground type is a type that has no parameters, modifiers, or substitutions. For example, i32 or String.

  1. What is Universal Function Call syntax?

Universal Function Call syntax is used to disambiguate functions or methods. It looks like Foo::f(&b) instead of b.f().

  1. What are the possible type signatures of a trait object?

A trait object is any signature for a trait that will give it a known size at compile time. Common examples of this are &Trait or Box<Trait>.

  1. What are two ways to obscure type information...
