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.

In this chapter, we covered the remainder of the essential non-atomic Rust synchronization primitives, doing a deep-dive on the postmates/hopper libraries to explore their use in a production code base. After having digested Chapter 4, Sync and Send – the Foundation of Rust Concurrency, and this chapter, the reader should be in a fine position to build lock-based, concurrent data structures in Rust. For readers that need even more performance, we'll explore the topic of atomic programming in Chapter 6, Atomics – the Primitives of Synchronization, and in Chapter 7, Atomics – Safely Reclaiming Memory.

If you thought lock-based concurrency was hard, wait  until you see atomics.
