Struct google_pubsub1::api::ReceivedMessage

pub struct ReceivedMessage {
    pub ack_id: Option<String>,
    pub delivery_attempt: Option<i32>,
    pub message: Option<PubsubMessage>,
}

A message and its corresponding acknowledgment ID.

This type is not used in any activity, and only used as part of another schema.

Fields

ack_id: Option<String>

Optional. This ID can be used to acknowledge the received message.

delivery_attempt: Option<i32>

Optional. The approximate number of times that Pub/Sub has attempted to deliver the associated message to a subscriber. More precisely, this is 1 + (number of NACKs) + (number of ack_deadline exceeds) for this message. A NACK is any call to ModifyAckDeadline with a 0 deadline. An ack_deadline exceeds event is whenever a message is not acknowledged within ack_deadline. Note that ack_deadline is initially Subscription.ackDeadlineSeconds, but may get extended automatically by the client library. Upon the first delivery of a given message, delivery_attempt will have a value of 1. The value is calculated at best effort and is approximate. If a DeadLetterPolicy is not set on the subscription, this will be 0.

message: Option<PubsubMessage>

Optional. The message.
