How to use the placebo.pill.serialize function in placebo

result["second"] = obj.second
        result["microsecond"] = obj.microsecond
        return result
    if isinstance(obj, StreamingBody):
        result["body"] = obj.read()
        obj._raw_stream = StringIO(result["body"])
        obj._amount_read = 0
        return result
    if isinstance(obj, bytes):
        return obj.decode('utf8')

    # Raise a TypeError if the object isn't recognized
    raise TypeError("Type not serializable")


placebo.pill.serialize = serialize
placebo.pill.deserialize = deserialize
