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.

Summary


In this chapter, you learned how the processor really works. You understood the multiple hacks we have in the hardware so that everything runs much, much faster than it would if the CPU was always waiting for the RAM. You also got a grasp of the most common performance issues and some information on how to fix them.

Finally, you learned about the Callgrind, Cachegrind, and OProfile tools, which will help you find those bottlenecks so that you can fix them easily. They will even show where in your source code you can find the slowdowns.

In Chapter 6Benchmarking, you will learn how to benchmark your application. It is especially interesting to compare it to other applications or to a previous version of your own application. You will learn how to spot changes that make your application slower.
