This book will introduce you to the development of microservices with Rust. I started using Rust not that long ago, back in 2015. It had only been a couple of months since the release of version 1.0 and, at that time, I didn't think that this tool would usher in a silent revolution that would disrupt the traditions associated with system programming, which, at that time, was tedious and in no way fashionable.

Maybe I'm exaggerating a little, but I have witnessed how companies stopped using the customary tools and began rewriting parts of their products or a number of services in Rust, and they were so happy with the outcome that they continue to do so time and again. Today, Rust is an important part of blockchain initiatives, the flagship for WebAssembly, and is an awesome tool for developing fast and reliable microservices that utilize all available server resources. Consequently, Rust has transformed itself from a hobby tool for curious developers into a strong foundation for modern products.

In this book, we will learn how to create microservices using Rust. We begin with a short introduction to microservices, and discuss why Rust is a good tool for writing them. Then, we will create our first microservice using the hyper crate, and learn how to configure microservices and log activities. After that, we will explore how to support different formats of requests and responses using the serde crate.
