Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Exploring TCP

TCP stands for transmission control protocol. TCP is one of the most widely used transfer protocols on the internet. TCP is essentially a protocol that transports bytes over a socket from one program or computer to another using an internet protocol (IP). TCP is used for the world wide web, email, remote administration, and file transfer. The transport layer security/secure sockets layer (TLS/SSL) protocols are built on top of TCP. This means that HTTP and HTTPS are built on top of TCP.

TCP is a connection-oriented protocol. This is where a connection between the client and server is established before any data is transferred. This is achieved by a three-way handshake:

  1. SYN: Initially, the client sends a SYN to the server. The SYN is a message with a random number to ensure that the same client is communicating with the server.
  2. SYN-ACK: The server then responds to the client with the initial sequence number and an additional random number known as the ACK...
