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

Introduction to FTP and TFTP

Another common application layer protocol is the File Transfer Protocol (FTP). This is a text-based protocol, where the server and clients exchange text commands to upload and download files. The Rust ecosystem has a crate called rust-ftp to interact with FTP servers programmatically. Let us look at an example of its use. We set up our project using Cargo:

$ cargo new --bin ftp-example

Our Cargo.toml should look like this:

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

version = "2.2.1"

For this example to work, we will need a running FTP server somewhere. Once we have set that up and made sure a regular FTP client can connect to it, we can move on to our main code:

// ch5/ftp-example/src/

extern crate ftp;

use std::str;
use std::io::Cursor;
use ftp::{FtpStream...
