                default endpoint provided by the client when ``transport`` is
                not explicitly provided. Only if this property is not set and
                ``transport`` was not explicitly provided, the endpoint is
                determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment

                "always" (always use the default mTLS endpoint), "never" (always
                use the default regular endpoint) and "auto" (auto-switch to the
                default mTLS endpoint if client certificate is present; this is
                the default value).

                2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
                is "true", then the ``client_cert_source`` property can be used
                to provide a client certificate for mTLS transport. If
                not provided, the default SSL client certificate will be used if
                present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
                set, no client certificate will be used.

                3. The ``universe_domain`` property can be used to override the
                default "googleapis.com" universe. Note that ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

                Required. The content of the current conversation with
                the ``Model``. For single-turn queries, this is a single
                question to answer. For multi-turn queries, this is a
                repeated field that contains conversation history and
                the last ``Content`` in the list containing the
                question.

                Note: ``GenerateAnswer`` only supports queries in
                English.

                This corresponds to the ``contents`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            safety_settings (:class:`MutableSequence[google.ai.generativelanguage_v1beta.types.SafetySetting]`):
                Optional. A list of unique ``SafetySetting`` instances
                for blocking unsafe content.

                This will be enforced on the
                ``GenerateAnswerRequest.contents`` and
                ``GenerateAnswerResponse.candidate``. There should not
                be more than one setting for each ``SafetyCategory``
                type. The API will block any contents and responses that
                fail to meet the thresholds set by these settings. This
                list overrides the default settings for each
                ``SafetyCategory`` specified in the safety_settings. If
                there is no ``SafetySetting`` for a given
                ``SafetyCategory`` provided in the list, the API will
                use the default safety setting for that category. Harm
                categories HARM_CATEGORY_HATE_SPEECH,
                HARM_CATEGORY_SEXUALLY_EXPLICIT,
                HARM_CATEGORY_DANGEROUS_CONTENT,
                HARM_CATEGORY_HARASSMENT are supported. Refer to the
                `guide <https://ai.google.dev/gemini-api/docs/safety-settings>`__
                for detailed information on available safety settings.
                Also refer to the `Safety
                guidance <https://ai.google.dev/gemini-api/docs/safety-guidance>`__
                to learn how to incorporate safety considerations in
                your AI applications.

                This corresponds to the ``safety_settings`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            answer_style (:class:`google.ai.generativelanguage_v1beta.types.GenerateAnswerRequest.AnswerStyle`):
                Required. Style in which answers
                should be returned.

                This corresponds to the ``answer_style`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry_async.AsyncRetry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.
