parse()

std::optional< InputValue > MayaFlux::Core::OscParser::parse ( const uint8_t *  data, size_t  size, uint32_t  device_id = 0  )

static

Parse a single OSC message from raw bytes.

Parameters

data	Pointer to datagram payload.
size	Payload size in bytes.
device_id	Device id to stamp on the resulting InputValue.

Returns

Parsed InputValue with Type::OSC, or nullopt on parse failure.
