Hands-On Concurrency with Rust

By: Brian L. Troutwine

Overview of this book

Most programming languages can really complicate things, especially with regard to unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and your language's pain-points. This book will teach you to how to manage program performance on modern machines and build fast, memory-safe, and concurrent software in Rust. It starts with the fundamentals of Rust and discusses machine architecture concepts. You will be taken through ways to measure and improve the performance of Rust code systematically and how to write collections with confidence. You will learn about the Sync and Send traits applied to threads, and coordinate thread execution with locks, atomic primitives, data-parallelism, and more. The book will show you how to efficiently embed Rust in C++ code and explore the functionalities of various crates for multithreaded applications. It explores implementations in depth. You will know how a mutex works and build several yourself. You will master radically different approaches that exist in the ecosystem for structuring and managing high-scale systems. By the end of the book, you will feel comfortable with designing safe, consistent, parallel, and high-performance applications in Rust.

Further reading

  • FFI examples written in Rust, available at This repository by Alex Crichton is a well-done collection of FFI examples in Rust. The documentation in this book on this topic is quite good, but it never hurts to pour through working code.
  • Hacker's Delight, Henry Warren Jr. If you enjoyed the bit fiddling present in this chapter's take on feruscore, you'll love Hacker's Delight. It's old now and some of its algorithms no longer function on 64-bit words, but it's still well worth reading, especially if you, like me, work to keep fixed-width types as small as possible.
  • Foreign Function Interface, available at The Nomicon builds a higher-level wrapper for the compression library snappy. This wrapper is extended in ways we did not touch on here, specifically with regard to C callbacks and vardic function calls.
  • Global Interpreter Lock, available at
