Modelling A Ticket, pt. 2

The Ticket struct we worked on in the previous chapters is a good start, but it still screams "I'm a beginner Rustacean!".

We'll use this chapter to refine our Rust domain modelling skills. We'll need to introduce a few more concepts along the way:

• enums, one of Rust's most powerful features for data modeling
• The Option type, to model nullable values
• The Result type, to model recoverable errors
• The Debug and Display traits, for printing
• The Error trait, to mark error types
• The TryFrom and TryInto traits, for fallible conversions
• Rust's package system, explaining what's a library, what's a binary, how to use third-party crates
