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.

Clippy


If there is a tool that will help you sanitize your code the most, it is Clippy. At the time of writing, Clippy provides 208 extra lints, most of them really useful to avoid interesting pitfalls such as the unwrap_or() usage that we discussed in Chapter 2Extra Performance Enhancements, or to avoid non-idiomatic code. Of course, we will not see all of them here, and you will find a comprehensive list of all of them in the Clippy lint documentation at https://rust-lang-nursery.github.io/rust-clippy/master/.

Since many of them already warn or even deny by default, we will check some of the ones that are allowed by default but that could be really useful to improve the code quality of your application and even its performance.

Installation

Installing Clippy is pretty easy: you will need to install Rust nightly by running rustup toolchain install nightly, then you can install Clippy by running cargo +nightly install clippy.

Note that since Clippy requires a nightly compiler to build, and...
