-- | Creates a value of 'DescribeVPCEndpoints' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'dvpceFilters' - One or more filters.     * @service-name@ : The name of the AWS service.     * @vpc-id@ : The ID of the VPC in which the endpoint resides.     * @vpc-endpoint-id@ : The ID of the endpoint.     * @vpc-endpoint-state@ : The state of the endpoint. (@pending@ | @available@ | @deleting@ | @deleted@ )
--
-- * 'dvpceNextToken' - The token for the next set of items to return. (You received this token from a prior call.)
--
-- * 'dvpceVPCEndpointIds' - One or more endpoint IDs.
--
-- * 'dvpceDryRun' - Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is @DryRunOperation@ . Otherwise, it is @UnauthorizedOperation@ .
--
-- * 'dvpceMaxResults' - The maximum number of items to return for this request. The request returns a token that you can specify in a subsequent call to get the next set of results. Constraint: If the value is greater than 1000, we return only 1000 items.
