16	// return an error, this is because in case of error (i.e. when
17	// RecvPacketResult.Status == Failure), the underlying transaction is not
18	// aborted. So implementer of this interface must keep in mind that any
19	// writes to the store and all emitted events in this function aren't not
20	// canceled if it returns RecvPacketResult.Status == Failure.
