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've discussed the preliminaries of this book, the machine architecture of modern CPUs, and the way loads and stores of memory may be interleaved for surprising results, illustrating the need for some kind of synchronization for our computations. That need for synchronization will drive much of the discussion of this book. We also discussed installing Rust, the channels of the compiler itself, and our intention to focus on the stable channel. We also compiled a simple program for both x86 and ARM systems. We also discussed debugging and performance analysis of our simple program, mostly as a proof-of-concept of the tools. The next chapter, Chapter 2, Sequential Rust Performance and Testing, will explore this area in much more depth.
