messages

Message classes for explicit typing and the sanity of clear expectations

class perceptivo.networking.messages.Message(message_number: Optional[int] = None, timestamp: Optional[datetime.datetime] = None, key: str = '', **kwargs)

Bases: perceptivo.root.Perceptivo_Object

Message container implementing msgpack-based numpy array de/serialization.

Subclass this to make specific message types!

Parameters

**kwargs (dict) – key/value pairs stored in Message.value

Attrs:

value (dict): (deserialized) dictionary of values passed from **kwargs

counter = count(0)

__init__(message_number: Optional[int] = None, timestamp: Optional[datetime.datetime] = None, key: str = '', **kwargs)

Parameters

**kwargs (dict) – key/value pairs stored in Message.value

Attrs:

value (dict): (deserialized) dictionary of values passed from **kwargs

serialize(msg: Optional[dict] = None) → bytes

classmethod from_serialized(msg: bytes) → perceptivo.networking.messages.Message

Create an instance of Message from a msgpack serialized bytestring
