In a sequential programming model, code is always executed in the order dictated by the semantics of the programming language. Thus, if one operation blocks for some reason (waiting for a resource, and so forth), the whole execution blocks and can only move forward once that operation has completed. This often leads to poor utilization of resources, because the main thread will be busy waiting on one operation. In GUI apps, this also leads to poor user interactivity, because the main thread, which is responsible for managing the GUI, is busy waiting for something else. This is a major problem in our specific case of network programming, as we often need to wait for data to be available on a socket. In the past, we worked around these issues using multiple threads. In that model, we delegated a costly operation to a background thread...

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
