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...
