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 8. High-Level Parallelism – Threadpools, Parallel Iterators and Processes

In previous chapters, we introduced the basic mechanisms of concurrency in the Rust—programming language. In Chapter 4, Sync and Send – the Foundation of Rust Concurrency, we discussed the interplay of the type system of Rust with concurrent programs, how Rust ensures memory safety in this most difficult of circumstances. In Chapter 5, Locks – Mutex, Condvar, Barriers and RWLock, we discussed the higher, so-called coarse, synchronization mechanisms available to us, common among many languages. In Chapter 6, Atomics – the Primitives of Synchronization, and Chapter 7, Atomics – Safely Reclaiming Memory, we discussed the finer synchronization primitives available on modern machines, exposed through Rust's concurrent memory model. This has all been well and good but, though we've done deep-dives into select libraries or data structures, we have yet to see the consequences of all of these tools on the structure...
