Enum AckOutcome 

pub enum AckOutcome {
    Acknowledged(HostDeliveryRecord),
    AlreadyAcknowledged(HostDeliveryRecord),
    Conflict {
        existing: Box<HostDeliveryObservation>,
    },
    LeaseNotOwned,
}

What the ledger did with a host’s report about a delivery.

The four answers are deliberately different things. A repeat of the same report is the same fact arriving twice and costs nothing; a different report about a delivery already acknowledged is two hosts disagreeing and must not be flattened into the later one; and a lease that is not the current one is a host that was replaced while it was away, whose answer arrives too late to be worth anything.

Variants

Acknowledged(HostDeliveryRecord)

Recorded.

AlreadyAcknowledged(HostDeliveryRecord)

The same report, already recorded.

Conflict

A different report about a delivery that is already acknowledged.

Fields

existing: Box<HostDeliveryObservation>

LeaseNotOwned

The lease offered is not the one that holds this delivery.
