[rabbitmq-discuss] opposite of basicAck?

[tsuraan]

If I have a message that I know that I don't want to handle right now,
is there something like basicAck that rejects a deliveryTag instead of
acking it?  IIRC, after some timeout, or a channel close, the message
will be queued for redelivery, but I have a case where I know that a
message I received isn't useful for me yet, so I'd like to immediately
reject it so I can pick it up later.  Is that possible?
