def __format__ : IO::ByteFormat #

A group or bit_field captures the endianness at its declaration point, so declaring endian after one would silently leave it system-endian. Fail loudly.

NOTE : raises if the broker rejected any of the topic filters, use #raw_return_codes when a rejection is possible
