def basic_reject(self, delivery_tag, requeue):
        """Reject an incoming message

        This method allows a client to reject a message.  It can be
        used to interrupt and cancel large incoming messages, or
        return untreatable messages to their original queue.

        RULE:

            The server SHOULD be capable of accepting and process the
            Reject method while sending message content with a Deliver
            or Get-Ok method.  I.e. the server should read and process
            incoming methods while sending output frames.  To cancel a
            partially-send content, the server sends a content body
            frame of size 1 (i.e. with no data except the frame-end
            octet).

        RULE:

            The server SHOULD interpret this method as meaning that
            the client is unable to process the message at this time.

        RULE:

            A client MUST NOT use this method as a means of selecting
            messages to process.  A rejected message MAY be discarded
            or dead-lettered, not necessarily passed to another
            client.

        PARAMETERS:
            delivery_tag: longlong

                server-assigned delivery tag

                The server-assigned and channel-specific delivery tag

                RULE:

                    The delivery tag is valid only within the channel
                    from which the message was received.  I.e. a client
                    MUST NOT receive a message on one channel and then
                    acknowledge it on another.

                RULE:

                    The server MUST NOT use a zero value for delivery
                    tags.  Zero is reserved for client use, meaning "all
                    messages so far received".

            requeue: boolean

                requeue the message

                If this field is False, the message will be discarded.
                If this field is True, the server will attempt to
                requeue the message.

                RULE:

                    The server MUST NOT deliver the message to the
                    same client within the context of the current
                    channel.  The recommended strategy is to attempt
                    to deliver the message to an alternative consumer,
                    and if that is not possible, to move the message
                    to a dead-letter queue.  The server MAY use more
                    sophisticated tracking to hold the message on the
                    queue and redeliver it to the same client at a
                    later stage.
