Because SeqCst is good enough for most applications and the complexity involved in all other orderings, we are not going to look at any others. Don't be disappointed, however—Rust uses nearly the same atomic layout and functionality as C++, so there are plenty of sources to tell you how complex the issue really is. Anthony Williams, author of the well-known book C++: Concurrency In Action (http://www.cplusplusconcurrencyinaction.com/), uses an entire 45 pages (!) to simply describe all the atomic orderings and how to use them. An additional 44 pages go into showing examples of all of these orderings. Does an average program benefit from this level of dedication? Let's look at the man's own words, with the background knowledge that std::memory_order_seq_cst is how C++ calls SeqCst:

Overview of this book
Mozilla’s Rust is gaining much attention with amazing features and a powerful library. This book will take you through varied recipes to teach you how to leverage the Standard library to implement efficient solutions.
The book begins with a brief look at the basic modules of the Standard library and collections. From here, the recipes will cover packages that support file/directory handling and interaction through parsing. You will learn about packages related to advanced data structures, error handling, and networking. You will also learn to work with futures and experimental nightly features. The book also covers the most relevant external crates in Rust.
By the end of the book, you will be proficient at using the Rust Standard library.
