Enum BookOutcome 

pub enum BookOutcome {
    Booked,
    SlotTaken,
    Unavailable,
}

What came of trying to book one slot.

Variants

Booked

It is in the calendar; the caller has an appointment.

SlotTaken

Somebody else took it between the offer and the keypress. Worth its own answer because the caller can be offered something else, where Unavailable means asking again is pointless.

Unavailable

The booking could not be attempted or did not stick — no connection, a provider outage, a refused request.
