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 Hyper

Hyper is arguably the most stable and well-known of Rust-based HTTP frameworks. It has two distinct components, one for writing HTTP servers and one for writing clients. Recently, the server component was moved to a new async programming model based on tokio and futures. As a result, it is well-suited for high-traffic workloads. However, like a lot of other libraries in the ecosystem, Hyper has not hit Version 1.0 yet, so one should expect breaking API changes.

We will start with writing a small HTTP server in Hyper. Like always, we will need to set up our project using Cargo.

$ cargo new --bin hyper-server

Let us now add dependencies that will include hyper and futures. The Cargo.toml file will look as follows:

name = "hyper-server"
version = "0.1.0"
authors = ["Foo<[email protected]>"]

hyper = "0.11.7&quot...
