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 4. Lints and Clippy

Up until now, we needed to check all the details of the code by ourselves. This can often get out of control, since we cannot be checking each line of code. In this chapter, you will learn about the lints Rust brings us, both the ones enabled by default and the ones you can enable yourself.

Moreover, you will learn about a great tool, Clippy, that will give you many more lints you can use, and that can help you write much better code. In many cases, it will lint about performance pitfalls. In other cases, they will be potential errors or idiomatic conventions. It will also help you clean your code.

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

  • Linting in Rust
  • Default lints
  • Using and configuring Clippy
  • Extra Clippy lints
