Network Programming with Rust

By: Abhishek Chanda

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

Generics and the trait system

Rust supports writing generic code that is later bound with more concrete types, either during compile time or during runtime. People who are familiar with templates in C++ might notice that generics in Rust are pretty similar to templates, as far as syntax goes. The following example illustrates how to use generic programming. We also introduce some new constructs which we haven't discussed before, which we will explain as we proceed.

Much like C and C++, a Rust struct defines a user-defined type that aggregates multiple logically connected resources in one unit. Our struct here defines a tuple of two variables. We define a generic struct and we use a generic type parameter, written here as <T>. Each member of the struct is defined to be of that type. We later define a generic function that sums the two elements of the tuple. Let&apos...
