You'll now start to model the business domain. No low level systems programming here, let's build something real together.

• Register a new account
• Login
• Retrieve their account information
• Update their account details

Which means you need to model a User. Users are also going to need properties, you know things like first_name, last_name. So let's look at the different data types available in Rust that you'll use.
