Enum DeliverySemantics 

pub enum DeliverySemantics {
    AtMostOnce,
    AtLeastOnce,
    ExactlyOnce,
    BestEffort,
}

Delivery guarantee explicitly stated by a contract or source call.

Variants

AtMostOnce

A message may be lost but is not intentionally redelivered.

AtLeastOnce

A message may be redelivered until it is acknowledged.

ExactlyOnce

The declaration explicitly claims exactly-once processing or delivery.

BestEffort

The declaration explicitly describes best-effort delivery.
