Already popular among programmers for its memory safety and speed, the Rust programming language is also valuable for asynchrony. This practical book shows you how asynchronous Rust can help you solve problems that require multitasking. You'll learn how to apply async programming to solve problems with an async approach. You will also dive deeper into async runtimes, implementing your own ways in which async runtimes handle incoming tasks.

Authors Maxwell Flitton and Caroline Morton also show you how to implement the Tokio software library to help you with incoming traffic, communicate between threads with shared memory and channels, and design a range of complex solutions using actors. You'll also learn to perform unit and end-to-end tests on a Rust async system.

With this book, you'll learn:

How Rust approaches async programming
How coroutines relate to async Rust
Reactive programming and how to implement pub sub in async rust
How to solve problems using actors
How to customize Tokio to gain control over how tasks are processed
Async Rust design patterns
How to build an async TCP server just using the standard library
How to unit test async Rust

Asynchronous programming in Rust, often referred to as Async Rust, is a powerful paradigm that allows developers to write concurrent code that is more efficient and scalable. In contrast to traditional synchronous programming, where tasks are executed one after another, async programming enables tasks to run concurrently, which is particularly useful when dealing with I/O-bound operations like network requests or file handling. This approach allows for the efficient use of system resources and can lead to significant performance improvements in applications that need to handle multiple tasks at once without the need for additional cores.

Rust’s type system and ownership model provide the safety guarantees that we all love. However, mastering async Rust requires an understanding of specific concepts, such as futures, pinning, and executors. This book will guide you through these concepts, equipping you with the knowledge needed to apply async to your own projects and programs.

Who Is This Book For?
This book is aimed at intermediate Rust developers who want to learn how to improve their applications and programs by using the range of asynchronous functionality available to them.

By the end of the book, you'll be able to implement your own async TCP server completely from the standard library with zero external dependencies, and unit test your async code.
