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.

Chapter 3. The Rust Memory Model – Ownership, References and Manipulation

In the previous chapter, Chapter 2, Sequential Rust Performance and Testing, we discussed factors that contribute or detract from the serial performance of a Rust program. We did not explicitly address concurrent performance for want of sufficient information about the way Rust's abstract memory model interacts with the real memory hierarchy of a machine. In this chapter, we'll discuss Rust's memory model, how to control the layout of types in memory, how types are aliased, and how Rust's memory safety works. We'll dig into the standard library to understand how this plays out in practice. This chapter will also examine common crates in the ecosystem that will be of interest to us later in this book. Please be aware that by the time you read this chapter, the rustc implementation will have changed, potentially making our code listings here no longer square with the naming patterns in rustc itself.
