                through which to make calls. This argument is mutually exclusive

        Args:
            parent (str): Required. The relative name of the root asset. This can only be an
                organization number (such as "organizations/123"), a project ID (such as
                "projects/my-project-id"), or a project number (such as "projects/12345"),
                or a folder number (such as "folders/123").
            output_config (Union[dict, ~google.cloud.asset_v1.types.OutputConfig]): Required. Output configuration indicating where the results will be output
                to. All results will be in newline delimited JSON format.

                If a dict is provided, it must be of the same form as the protobuf

                the current time will be used. Due to delays in resource data collection

                "compute.googleapis.com/Disk". If specified, only matching assets will
                be returned. See `Introduction to Cloud Asset
                Inventory <https://cloud.google.com/asset-inventory/docs/overview>`__
                for all supported asset types.
            content_type (~google.cloud.asset_v1.types.ContentType): Asset content type. If not specified, no content but the asset name will be
                returned.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will
                be retried using a default configuration.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.

                that is provided to the method.

                When an API method normally takes long time to complete, it can be
                designed to return ``Operation`` to the client, and the client can use
                this interface to receive the real response asynchronously by polling
                the operation resource, or pass the operation resource to another API
                (such as Google Cloud Pub/Sub API) to receive the response. Any API
                service that returns long-running operations should implement the
                ``Operations`` interface so developers can have a consistent client
                experience.

            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is

        Args:
            parent (str): Required. The name of the project/folder/organization where this feed
                should be created in. It can only be an organization number (such as
                "organizations/123"), a folder number (such as "folders/123"), a project ID
                (such as "projects/my-project-id")", or a project number (such as
                "projects/12345").
            feed_id (str): Required. This is the client-assigned asset feed identifier and it needs to
                be unique under a specific parent project/folder/organization.
            feed (Union[dict, ~google.cloud.asset_v1.types.Feed]): Each of the definitions above may have "options" attached. These are
                just annotations which may cause code to be generated slightly
                differently or may contain hints for code that manipulates protocol
                messages.

                Clients may define custom options as extensions of the \*Options
                messages. These extensions may not yet be known at parsing time, so the
                parser cannot store the values in them. Instead it stores them in a
                field in the \*Options message called uninterpreted_option. This field
                must have the same name across all \*Options messages. We then use this
                field to populate the extensions when we build a descriptor, at which
                point all protos have been parsed and so all extensions are known.

                Extension numbers for custom options may be chosen as follows:

                -  For options which will only be used within a single application or
                   organization, or for experimental options, use field numbers 50000
                   through 99999. It is up to you to ensure that you do not use the same
                   number for multiple options.
                -  For options which will be published and used publicly by multiple
                   independent entities, e-mail
                   protobuf-global-extension-registry@google.com to reserve extension
                   numbers. Simply provide your project name (e.g. Objective-C plugin)
                   and your project website (if available) -- there's no need to explain
                   how you intend to use them. Usually you only need one extension
                   number. You can declare multiple options with only one extension
                   number by putting them in a sub-message. See the Custom Options
                   section of the docs for examples:
                   https://developers.google.com/protocol-buffers/docs/proto#options If
                   this turns out to be popular, a web service will be set up to
                   automatically assign option numbers.

                serialized protocol buffer message. This string must contain at least
                one "/" character. The last segment of the URL's path must represent the
                fully qualified name of the type (as in
                ``path/google.protobuf.Duration``). The name should be in a canonical
                form (e.g., leading "." is not accepted).

                In practice, teams usually precompile into the binary all types that
                they expect it to use in the context of Any. However, for URLs which use
                the scheme ``http``, ``https``, or no scheme, one can optionally set up
                a type server that maps type URLs to message definitions as follows:

                -  If no scheme is provided, ``https`` is assumed.
                -  An HTTP GET on the URL must yield a ``google.protobuf.Type`` value in
                   binary format, or produce an error.
                -  Applications are allowed to cache lookup results based on the URL, or
                   have them precompiled into a binary to avoid any lookup. Therefore,
                   binary compatibility needs to be preserved on changes to types. (Use
                   versioned type names to manage breaking changes.)

                Note: this functionality is not currently available in the official
                protobuf release, and it is not used for type URLs beginning with
                type.googleapis.com.

                Schemes other than ``http``, ``https`` (or the empty scheme) might be
                used with implementation specific semantics.

        Args:
            name (str): A list of the full names of the assets. For example:
                ``//compute.googleapis.com/projects/my_project_123/zones/zone1/instances/instance1``.
                See `Resource
                Names <https://cloud.google.com/apis/design/resource_names#full_resource_name>`__
                and `Resource Name
                Format <https://cloud.google.com/asset-inventory/docs/resource-name-format>`__
                for more info.

                The request becomes a no-op if the asset name list is empty, and the max
                size of the asset name list is 100 in one request.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will
                be retried using a default configuration.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
