This chapter was a short introduction to the basic networking functionality in Rust. We started with given functionality in std::net, and we wrote a few TCP and UDP servers using those. We then looked at some other utilities in the same namespace. At the end, we went over examples of a number of crates which are aimed at extending the standard library's functionality around networking. Bear in mind that it is always possible to just use the libc crate to write networking code, which is based on POSIX-compatible networking code with access to fine-grained control over sockets and network devices. The problem with this approach is that the code might be unsafe, breaking Rust's guarantee of safety. Another crate called nix aims to provide libc's functionality native Rust so that it preserves all the memory and type safety guarantees that the compiler provides...

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
