                Custom options for the client.

                1. The ``api_endpoint`` property can be used to override the
                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
                variable, which have one of the following values:
                "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 the ``api_endpoint``
                property still takes precedence; and ``universe_domain`` is

                on the ``request`` instance; if ``request`` is provided, this

            retry (google.api_core.retry.Retry): Designation of what errors, if any,

            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, Union[str, bytes]]]): Key/value pairs which should be
                sent along with the request as metadata. Normally, each value must be of type `str`,

                ``name`` and output only fields cannot be updated.

                At some point in the future, behavior will be removed

                The request object. The parameters to ``UpdateExclusion``.
            name (str):
                Required. The resource name of the exclusion to update:

                ::

                    "projects/[PROJECT_ID]/exclusions/[EXCLUSION_ID]"

                    "folders/[FOLDER_ID]/exclusions/[EXCLUSION_ID]"

                For example:

                ``"projects/my-project/exclusions/my-exclusion"``

                This corresponds to the ``name`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            exclusion (google.cloud.logging_v2.types.LogExclusion):
                Required. New values for the existing exclusion. Only
                the fields specified in ``update_mask`` are relevant.

                This corresponds to the ``exclusion`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            update_mask (google.protobuf.field_mask_pb2.FieldMask):
                Required. A non-empty list of fields to change in the
                existing exclusion. New values for the fields are taken
                from the corresponding fields in the
                [LogExclusion][google.logging.v2.LogExclusion] included
                in this request. Fields not mentioned in ``update_mask``
                are not changed and are ignored in the request.

                For example, to change the filter and description of an
                exclusion, specify an ``update_mask`` of
                ``"filter,description"``.

                This corresponds to the ``update_mask`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, Union[str, bytes]]]): Key/value pairs which should be
                sent along with the request as metadata. Normally, each value must be of type `str`,
                but for metadata keys ending with the suffix `-bin`, the corresponding values must
                be of type `bytes`.

            google.cloud.logging_v2.types.LogExclusion:
                Specifies a set of log entries that are filtered out by a sink. If
                   your Google Cloud resource receives a large volume of
                   log entries, you can use exclusions to reduce your
                   chargeable logs. Note that exclusions on
                   organization-level and folder-level sinks don't apply
                   to child resources. Note also that you cannot modify
                   the Required sink or exclude logs from it.
