Low-Level Concurrency in Practice
Mara Bos
Rust Atomics and Locks
The Rust programming language is extremely well suited
for concurrency, and its ecosystem has many libraries that
include lots of concurrent data structures, locks, and more.
But implementing those structures correctly can be difficult.
Even in the most well-used libraries, memory ordering bugs
are not uncommon.
In this practical book, Mara Bos, team lead of the Rust
library team, helps Rust programmers of all levels gain a
clear understanding of low-level concurrency. You’ll learn
everything about atomics and memory ordering and how
they’re combined with basic operating system APIs to build
common primitives like mutexes and condition variables.
Once you’re done, you’ll have a firm grasp of how Rust’s
memory model, the processor, and the role of the operating
system all fit together.
With this guide, you’ll learn:
“This book is incredible!
It’s exactly what I wanted
The Rustonomicon
to
cover on concurrency,
but far better than I
dared dream. Thorough
in all the right places.
Mara deserves a big
rest after this.”

Mara Bos
maintains the Rust standard
library and builds real-time control
systems in Rust. As team lead of the
Rust library team, she knows all the
ins and outs of the language and the
standard library. In addition, she’s been
working with concurrent real-time
systems for years as founder and CTO
at Fusion Engineering. Maintaining the
most used library in the Rust ecosystem
and working daily on safety critical
systems has given her the hands-on
experience to both understand the
theory and bring it into practice.

To all the Rust contributors who were waiting for me to
review their code while I was busy writing this book.
And to my loved ones, too, of course.
