Functions
DeviceParameterValue	mm::node::defaultValueForDataType (uint16_t dataType)
	Returns a zero-equivalent value for the given ETG.1020 dataType.
bool	mm::node::isScalarDataType (uint16_t dataType)
	Whether a value of dataType is stored in DeviceParameter::bits.
size_t	mm::node::scalarByteWidth (uint16_t dataType)
	Width in bytes of a value of dataType, or 0 when it is not a scalar.
uint64_t	mm::node::packLeBits (std::span< const uint8_t > bytes)
	Packs up to eight raw little-endian wire bytes into a uint64_t (zero-extended).
void	mm::node::unpackLeBits (uint64_t bits, std::span< uint8_t > out)
	Unpacks bits into out, little-endian. The inverse of packLeBits.
std::expected< DeviceParameterValue, std::string >	mm::node::decodeSdoBytes (uint16_t dataType, std::span< const uint8_t > bytes)
	Decodes a raw SDO byte sequence according to an ETG.1020 data type code.
std::expected< std::vector< uint8_t >, std::string >	mm::node::encodeSdoBytes (uint16_t dataType, const DeviceParameterValue &value)
	Serialises a DeviceParameterValue to raw SDO bytes — the inverse of decodeSdoBytes.
std::optional< double >	mm::node::numericValue (const DeviceParameterValue &value)
	Coerces a DeviceParameterValue to a double, when it holds a number.
std::string_view	mm::node::syncStateName (SyncState state)
	Returns the lowercase string form of state ("unknown" etc.).
std::string_view	mm::node::parameterOriginName (ParameterOrigin origin)
	Returns the string form of origin ("objectDictionary" / "sii").
void	mm::node::to_json (nlohmann::json &j, const DeviceParameter &p)
	Serialises a DeviceParameter to JSON.
