newRetainedMessageSummary :: RetainedMessageSummary Source #

Create a value of RetainedMessageSummary with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:lastModifiedTime:RetainedMessageSummary', retainedMessageSummary_lastModifiedTime - The Epoch date and time, in milliseconds, when the retained message was stored by IoT.

$sel:topic:RetainedMessageSummary', retainedMessageSummary_topic - The topic name to which the retained message was published.

$sel:qos:RetainedMessageSummary', retainedMessageSummary_qos - The quality of service (QoS) level used to publish the retained message.

$sel:payloadSize:RetainedMessageSummary', retainedMessageSummary_payloadSize - The size of the retained message's payload in bytes.

retainedMessageSummary_lastModifiedTime :: Lens' RetainedMessageSummary (Maybe Integer) Source #

The Epoch date and time, in milliseconds, when the retained message was stored by IoT.

retainedMessageSummary_topic :: Lens' RetainedMessageSummary (Maybe Text) Source #

The topic name to which the retained message was published.

retainedMessageSummary_qos :: Lens' RetainedMessageSummary (Maybe Natural) Source #

The quality of service (QoS) level used to publish the retained message.

retainedMessageSummary_payloadSize :: Lens' RetainedMessageSummary (Maybe Integer) Source #

The size of the retained message's payload in bytes.
