Struct PubsubMessage 

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

Available on crate features sink-pubsub or source-pubsub only.

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.

Fields

data: Vec<u8>

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

attributes: 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.

message_id: 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.

publish_time: Option<Timestamp>

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.

ordering_key: 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.
