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.

Debugging the Rust application

In the previous section, we learned about writing functional tests, but sometimes, the test fails. We want to know why the test failed. There are two possible places where the error might occur. One is in the user creation process, and the other is in finding users after creating the user.

One way to debug is by logging where the error might occur. If we log all the possible errors in the user creation process (for example, in src/routes/user.rs in the create_user() function), we will find out that the authenticity token verification sometimes produces an error. An example of logging the error is as follows:

csrf_token
    .verify(&new_user.authenticity_token)
    .map_err(|err| {
        log::error!("Verify authenticity_token error: {}", 
        err);
