Rust High Performance

By: Iban Eguia Moraza

Overview of this book

This book teaches you how to optimize the performance of your Rust code so that it is at the same level as languages such as C/C++. You'll understand and fi x common pitfalls, learn how to improve your productivity by using metaprogramming, and speed up your code. You will master the features of the language, which will make you stand out, and use them to greatly improve the efficiency of your algorithms. The book begins with an introduction to help you identify bottlenecks when programming in Rust. We highlight common performance pitfalls, along with strategies to detect and resolve these issues early. We move on to mastering Rust's type system, which will enable us to optimize both performance and safety at compile time. You will learn how to effectively manage memory in Rust, mastering the borrow checker. We move on to measuring performance and you will see how this affects the way you write code. Moving forward, you will perform metaprogramming in Rust to boost the performance of your code and your productivity. Finally, you will learn parallel programming in Rust, which enables efficient and faster execution by using multithreading and asynchronous programming.

Chapter 9. Creating Your Own Macros

In previous chapters, we saw how macros and metaprogramming, in general, can make your life much easier. We saw both, macros that reduce the required boilerplate code and macros that will speed up your final code. It's time for you to learn how to create your own macros.

In this chapter, you will learn how to create your own standard macros, how to create your own procedural macros and custom derives, and finally, how to use nightly features to create your own plugins. You will also see how the new declarative macros work.

The chapter is divided into three sections:

  • Macrosystem: Understanding the macro_rules!{} macro
  • Procedural macros: Learning how to create your own custom derives
  • Nightly metaprogramming: Plugins and declarative macros
