Class Method Summary

• .bit_fields

  A topic filter plus the 5.0 subscription options byte

Instance Method Summary

• #__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.

• #filter : String
• #filter=(filter : String)
• #filter_size : UInt16
