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

In this chapter, we covered measuring and improving the performance of a serial Rust program while demonstrating the program's fitness for purpose. This is a huge area of work and there's a deep well of literature to pull from.

  • Rust's std::collections is absolutely horrible, available at The original poster admitted the title is a bit on the click-baity side but the discussion on Reddit is well worth reading. The original author of standard library's HashMap weighs in on the design decisions in the implementation.
  • Robin Hood Hashing, 1985, Pedro Celis. This thesis introduced the Robin Hood hashing strategy for constructing associative arrays and is the foundation for the implementation you'll find in Rust. The paper also goes into further search strategies that didn't find their way into Rust's implementation but should be of interest to readers with ambitions toward building hashing...
