Validation

Let's go back to our ticket definition:

#![allow(unused)]
fn main() {
struct Ticket {
    title: String,
    description: String,
    status: String,
}
}

We are using "raw" types for the fields of our Ticket struct. This means that users can create a ticket with an empty title, a suuuuuuuper long description or a nonsensical status (e.g. "Funny").
We can do better than that!
