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.

Creating our first Rocket web application

In this section, we are going to create a very simple web application that handles only one HTTP path. Follow these steps to create our first Rocket web application:

  1. Create a new Rust application using Cargo:
    cargo new 01hello_rocket --name hello_rocket

We are creating an application named hello_rocket in a folder named 01hello_rocket.

  1. After that, let's modify the Cargo.toml file. Add the following line after [dependencies]:
    rocket = "0.5.0-rc.1"
  2. Append the following lines at the top of the src/main.rs file:
    #[macro_use]
    extern crate rocket;

Here, we are telling the Rust compiler to use macros from the Rocket crate by using the #[macro_use] attribute. We can skip using that attribute, but that would mean we must specify use for every single macro that we are going to use.

  1. Add the following line to tell the compiler that we are using the definition from the Rocket crate:
    use rocket::{Build...
