-- | Creates a value of 'DescribeVPNGateways' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'dvgsFilters' - One or more filters.     * @attachment.state@ - The current state of the attachment between the gateway and the VPC (@attaching@ | @attached@ | @detaching@ | @detached@ ).     * @attachment.vpc-id@ - The ID of an attached VPC.     * @availability-zone@ - The Availability Zone for the virtual private gateway (if applicable).     * @state@ - The state of the virtual private gateway (@pending@ | @available@ | @deleting@ | @deleted@ ).     * @tag@ :/key/ =/value/ - The key/value combination of a tag assigned to the resource.     * @tag-key@ - The key of a tag assigned to the resource. This filter is independent of the @tag-value@ filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the @tag@ :/key/ =/value/ filter.     * @tag-value@ - The value of a tag assigned to the resource. This filter is independent of the @tag-key@ filter.     * @type@ - The type of virtual private gateway. Currently the only supported type is @ipsec.1@ .     * @vpn-gateway-id@ - The ID of the virtual private gateway.
--
-- * 'dvgsVPNGatewayIds' - One or more virtual private gateway IDs. Default: Describes all your virtual private gateways.
--
-- * 'dvgsDryRun' - 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@ .
