 """ Exports assets with time and resource types to a given Cloud Storage location. The output format is newline-delimited JSON. This API implements the ``google.longrunning.Operation`` API allowing you to keep track of the export. Example: 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 message :class:`~google.cloud.asset_v1.types.OutputConfig` read_time (Union[dict, ~google.cloud.asset_v1.types.Timestamp]):
 Timestamp to take an asset snapshot. This can only be set to a timestamp between 2018-10-02 UTC (inclusive) and the current time. If not specified, the current time will be used. Due to delays in resource data collection and indexing, there is a volatile window during which running the same query may get different results. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.asset_v1.types.Timestamp` asset_types (list[str]):
 A list of asset types of which to take a snapshot for. For example: "compute.googleapis.com/Disk". If specified, only matching assets will be returned. See `Introduction to Cloud Asset Inventory <https://cloud.google.com/resource-manager/docs/cloud-asset-inventory/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 not be retried. 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. Returns: A :class:`~google.cloud.asset_v1.types._OperationFuture` instance. 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. """
