Serializes the protocol message to a binary string.

Keyword Args:
  deterministic (bool): If true, requests deterministic serialization
    of the protobuf, with predictable ordering of map keys.

Returns:
  A binary string representation of the message if all of the required
  fields in the message are set (i.e. the message is initialized).

Raises:
  EncodeError: if the message isn't initialized (see :func:`IsInitialized`).
