DeliveryMode¶
Bases: IntEnum
Enum for specifying the message delivery mode.
Inherits from :class:enum.IntEnum so members are usable wherever an
integer is expected, including the wire encoder for
:class:pika.spec.BasicProperties.delivery_mode.
Attributes: Transient: The message is not written to disk and may be lost if the broker crashes. Persistent: The message is written to disk and will survive broker crashes.
