Configuring our Rocket web application

Let's learn how to configure our Rocket web application, starting with different profiles for different situations. Then, we will use the Rocket.toml file to configure it. And finally, we will learn how to use environment variables to configure our application.

If you want to call the Cargo-installed application, you can use the full path or add it to your terminal path if you are using a Unix-based terminal. Append the following...
