Rust Web Programming - Second Edition

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.

Answers

  1. A closure is passed into the HttpServer::new function. The HttpServer::new function has to return the App struct so that the bind and run functions can be acted on them after the HttpServer::new function has fired.
  2. A closure can interact with variables outside of its scope.
  3. A process is a program that is being executed with its own memory stack, registers, and variables, whereas a thread is a lightweight process that is managed independently but shares data with other threads and the main program.
  4. A normal function executes as soon as it is called, whereas an async function is a promise and must be executed with a blocking function.
  5. await blocks a program to wait for a future to be executed; however, the join function can run multiple threads or futures concurrently. await can also be executed on a join function.
  6. Chaining factories gives us flexibility on how individual modules are constructed and orchestrated. A factory inside a module focuses on...
