Network Programming with Rust

Overview of this book

Rust is low-level enough to provide fine-grained control over memory while providing safety through compile-time validation. This makes it uniquely suitable for writing low-level networking applications. This book is divided into three main parts that will take you on an exciting journey of building a fully functional web server. The book starts with a solid introduction to Rust and essential networking concepts. This will lay a foundation for, and set the tone of, the entire book. In the second part, we will take an in-depth look at using Rust for networking software. From client-server networking using sockets to IPv4/v6, DNS, TCP, UDP, you will also learn about serializing and deserializing data using serde. The book shows how to communicate with REST servers over HTTP. The final part of the book discusses asynchronous network programming using the Tokio stack. Given the importance of security for modern systems, you will see how Rust supports common primitives such as TLS and public-key cryptography. After reading this book, you will be more than confident enough to use Rust to build effective networking software

Introducing Rocket

Perhaps the most widely known web framework for Rust is Rocket. It started as a one-man project and gradually evolved into a simple, elegant, and fast framework over the last year or so. Rocket focuses a lot on simplicity, something that a lot of Flask users will appreciate. Like Flask uses python decorators to declare routes, Rocket uses custom attributes to the same effect. Unfortunately, this means that Rocket has to make heavy use of nightly-only features. Thus, as of now, Rocket applications can only be built using nightly Rust. However, as more and more things are stabilized (moved to stable Rust), this restriction will eventually go away.

Let us start with a basic example of Rocket, beginning with setting up the project:

$ cargo new --bin rocket-simple

Our Cargo setup needs to add Rocket components as dependencies, and should look like this:
