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 6. Benchmarking

We have learned how to profile our application and how to find and fix the main bottlenecks, but there is another step in this process: checking whether our changes have improved the performance.

In this chapter, you will learn how to benchmark your application so that you can measure your improvements. This can meet two objectives: firstly, to check whether a new version of your application runs faster than an older version, and secondly, if you are creating a new application to solve a problem an existing application already solves, to compare the efficiency of your creation to the existing application.

In this context, you will learn about the following topics in this chapter:

  • Selecting what to benchmark
  • Benchmarking in nightly Rust
  • Benchmarking in stable Rust
  • Continuous integration for benchmarks
