Network Programming with Rust

This is the code repository for Network Programming with Rust, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

About the 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: 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. It takes an in-depth look at using Rust for networking software. Starting with 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 and implement 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.

Instructions and Navigation

All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, Chapter02.

There is no code in Chapter 1

The code will look like the following:

[package]
name = "hello-rust"
version = "0.1.0"
authors = ["Foo Bar <[email protected]>"]

They are either already familiar with Rust or are planning to start learning the language They have a commercial background in software engineering using other programming languages and are aware about the tradeoffs in developing software using different programming languages They have a basic familiarity with networking concepts They can appreciate why distributed systems are important in modern computing

Need to create an example code for Unix Domain Sockets

Hello,
This book gave me an overview of Network programming. It would be great if you also include unix domain sockets using UnixStream and UnixListener examples.

Chapter6, rocket is not worked.

Cargo run, got errors bellow:

    Updating crates.io index

Chapter3 - lookup_dns

https://github.com/PacktPublishing/Network-Programming-with-Rust/blob/master/Chapter03/lookup-host.rs

Could not compile the example from the book. (Also link above) Keep saying it cannot find lookup_dns. I'm on rust nightly.

However, I have managed to find a solution, so I thought I'll share it here.

First create a cargo project

cargo new lookup_dns

In the Cargo.toml, add the following to the dependencies

dns-lookup = "1.0.2"

Them add the following code:

use std::env;
use std::net::IpAddr;
use dns_lookup::lookup_host;

fn main() {
    let args: Vec<_> = env::args().collect();

    if args.len() != 2 {
        eprintln!("Please provide only one host name");
        std::process::exit(1);
    }
    else {
        let addresses: Vec<IpAddr> = lookup_host(&args[1]).unwrap();

        for address in addresses {
            println!("{}", address);
        }
    }
}

Build and execute the project

cargo build
cargo run google.co.uk

Chapter 6 Rocket-blog - Cannot run `cargo build`

Cannot run cargo build for Rocket-blog

Has anybody found a solution yet?
