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

Miscellaneous utilities in std::net

Another important type in the standard library is IpAddr, which represents an IP address. Not surprisingly, it is an enum with two variants, one for v4 addresses and the other for v6 addresses. All of these types have methods to classify addresses according to their types (global, loopback, multicast, and so on). Note that a number of these methods are not stabilized yet and hence are only available in the nightly compiler. They are behind a feature flag named ip which must be included in the crate root so that you can use those methods. A closely related type is SocketAddr, which is a combination of an IP address and a port number. Thus, this also has two variants, one for v4 and one for v6. Let's look at some examples:

use std::net::{IpAddr, SocketAddr};

fn main() {
// construct an IpAddr...
