How to use the azure-mgmt-devtestlabs.azure.mgmt.devtestlabs.models.ExportResourceUsageParameters function in azure-mgmt-devtestlabs

def _export_resource_usage_initial(
            self, resource_group_name, name, blob_storage_absolute_sas_uri=None, usage_start_date=None, custom_headers=None, raw=False, **operation_config):
        export_resource_usage_parameters = models.ExportResourceUsageParameters(blob_storage_absolute_sas_uri=blob_storage_absolute_sas_uri, usage_start_date=usage_start_date)

        # Construct URL
        url = self.export_resource_usage.metadata['url']
        path_format_arguments = {
            'subscriptionId': self._serialize.url("self.config.subscription_id", self.config.subscription_id, 'str'),
            'resourceGroupName': self._serialize.url("resource_group_name", resource_group_name, 'str'),
            'name': self._serialize.url("name", name, 'str')
        }
        url = self._client.format_url(url, **path_format_arguments)

        # Construct parameters
        query_parameters = {}
        query_parameters['api-version'] = self._serialize.query("self.api_version", self.api_version, 'str')

        # Construct headers
        header_parameters = {}
