parse static method

CodecParseResults parse(DC data, int offset, DistributedConnection? connection, List<int>? requestSequence, [ TransmissionType? dataType = null, ])

Parse a value

Bytes array Zero-indexed offset. Output the number of bytes parsed DistributedConnection is required in case a structure in the array holds items at the other end. DataType, in case the data is not prepended with DataType
