Network Programming with Rust

By: Abhishek Chanda

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

Some related crates

A careful reader might have noticed that a lot of common networking-related functionalities are missing from the standard library. For instance, there is no way to deal with IP networks (CIDRs). Let's look at how the ipnetwork crate helps with that. Since we are going to use an external crate, the example has to be in a cargo project. We will need to add it as a dependency to Cargo.toml. Let's start by setting up a project:

$ cargo new --bin ipnetwork-example

This generates a Cargo.toml file that we need to modify to declare our dependency. Once we do that, it should look like this:

name = "ipnetwork-example"
version = "0.1.0"
authors = ["Foo <[email protected]>"]

ipnetwork = "0.12.7"

Having set up the project, let's look at our main function:
