Hands-On Functional Programming in Rust
Andrew JohnsonFunctional 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.
