// TODO: A (derivable) trait implementation is missing for this exercise to compile successfully.

// Fix it!

// # `Debug` primer
|
|
//
|
|
// `Debug` returns a representation of a Rust type that's suitable for debugging (hence the name).
|
|
// `assert_eq!` requires `Ticket` to implement `Debug` because, when the assertion fails, it tries to
|
|
// print both sides of the comparison to the terminal.
|
|
// If the compared type doesn't implement `Debug`, it doesn't know how to represent them!
