    Args:
        message (SendableMessage): Message body to send.
            Can be any encodable object (native python types or `pydantic.BaseModel`).
        subject (str): NATS subject to send message (default is `''`).
        headers (:obj:`dict` of :obj:`str`: :obj:`str`, optional): Message headers to store metainformation (default is `None`).
            **content-type** and **correlation_id** will be set automatically by framework anyway.

        reply_to (str): NATS subject name to send response (default is `None`).
        correlation_id (str, optional): Manual message **correlation_id** setter (default is `None`).
            **correlation_id** is a useful option to trace messages.

        stream (str, optional): This option validates that the target subject is in presented stream (default is `None`).
            Can be omitted without any effect.
        timeout (float, optional): Timeout to send message to NATS in seconds (default is `None`).
        rpc (bool): Whether to wait for reply in blocking mode (default is `False`).
        rpc_timeout (float, optional): RPC reply waiting time (default is `30.0`).
        raise_timeout (bool): Whetever to raise `TimeoutError` or return `None` at **rpc_timeout** (default is `False`).
            RPC request returns `None` at timeout by default.

        _extra_middlewares (:obj:`Iterable` of :obj:`PublisherMiddleware`): Extra middlewares to wrap publishing process (default is `()`).
