Struct google_workflowexecutions1::api::PubsubMessage

pub struct PubsubMessage {
    pub attributes: Option<HashMap<String, String>>,
    pub data: Option<Vec<u8>>,
    pub message_id: Option<String>,
    pub ordering_key: Option<String>,
    pub publish_time: Option<DateTime<Utc>>,
}

A message that is published by publishers and consumed by subscribers. The message must contain either a non-empty data field or at least one attribute. Note that client libraries represent this object differently depending on the language. See the corresponding client library documentation for more information. See [quotas and limits] (https://cloud.google.com/pubsub/quotas) for more information about message limits.

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

Fields

attributes: Option<HashMap<String, String>>

Optional. Attributes for this message. If this field is empty, the message must contain non-empty data. This can be used to filter messages on the subscription.

data: Option<Vec<u8>>

Optional. The message data field. If this field is empty, the message must contain at least one attribute.

message_id: Option<String>

ID of this message, assigned by the server when the message is published. Guaranteed to be unique within the topic. This value may be read by a subscriber that receives a PubsubMessage via a Pull call or a push delivery. It must not be populated by the publisher in a Publish call.

ordering_key: Option<String>

Optional. If non-empty, identifies related messages for which publish order should be respected. If a Subscription has enable_message_ordering set to true, messages published with the same non-empty ordering_key value will be delivered to subscribers in the order in which they are received by the Pub/Sub system. All PubsubMessages published in a given PublishRequest must specify the same ordering_key value. For more information, see ordering messages.

publish_time: Option<DateTime<Utc>>

The time at which the message was published, populated by the server when it receives the Publish call. It must not be populated by the publisher in a Publish call.
