Struct SubscriberDeliveryToken 

Source 
pub struct SubscriberDeliveryToken(/* private fields */);
Expand description

Opaque subscriber-owned token attached to a delivered input batch.

Subscribers that provide durable, at-least-once delivery can use this token to identify the batch that becomes committable after runtime ingestion succeeds. The runtime never interprets the bytes. A token must be immutable, stable across replay, and must never identify two different batch payloads. Subscriber implementations must preserve delivery order while one token is awaiting acknowledgement; ReactiveEngine retries it before polling a later batch.
