Rust Web Development with Rocket

By: Karuna Murti

Overview of this book

Looking for a fast, powerful, and intuitive framework to build web applications? This Rust book will help you kickstart your web development journey and take your Rust programming skills to the next level as you uncover the power of Rocket - a fast, flexible, and fun framework powered by Rust. Rust Web Development with Rocket wastes no time in getting you up to speed with what Rust is and how to use it. You’ll discover what makes it so productive and reliable, eventually mastering all of the concepts you need to play with the Rocket framework while developing a wide set of web development skills. Throughout this book, you'll be able to walk through a hands-on project, covering everything that goes into making advanced web applications, and get to grips with the ins and outs of Rocket development, including error handling, Rust vectors, and wrappers. You'll also learn how to use synchronous and asynchronous programming to improve application performance and make processing user content easy. By the end of the book, you'll have answers to all your questions about creating a web application using the Rust language and the Rocket web framework.

Uploading a video post and process using a worker

In this section, we are going to process an uploaded video. Processing an uploaded video is not a trivial task as it can take a lot of time, so even with the async programming technique, the generated response will take a lot of time.

Another technique in programming to solve a long processing time is using message passing. We are going to create another thread to process the video. When a user uploads a video, we will do the following:

  1. Generate a path to the temporary file.
  2. Mark the path as unprocessed.
  3. Store the path to the file in the database.
  4. Send a message from the main Rocket thread into the thread for processing the video.
  5. Return the response for uploading the video.

If the thread to process the video receives a message, it will find the data from the database, process the file, and mark the post as finished.

If the user requests the posts list or posts while it's still being processed...
