-- | Creates a value of 'DescribeVPCPeeringConnections' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'dvpcpcFilters' - One or more filters.     * @accepter-vpc-info.cidr-block@ - The IPv4 CIDR block of the accepter VPC.     * @accepter-vpc-info.owner-id@ - The AWS account ID of the owner of the accepter VPC.     * @accepter-vpc-info.vpc-id@ - The ID of the accepter VPC.     * @expiration-time@ - The expiration date and time for the VPC peering connection.     * @requester-vpc-info.cidr-block@ - The IPv4 CIDR block of the requester's VPC.     * @requester-vpc-info.owner-id@ - The AWS account ID of the owner of the requester VPC.     * @requester-vpc-info.vpc-id@ - The ID of the requester VPC.     * @status-code@ - The status of the VPC peering connection (@pending-acceptance@ | @failed@ | @expired@ | @provisioning@ | @active@ | @deleting@ | @deleted@ | @rejected@ ).     * @status-message@ - A message that provides more information about the status of the VPC peering connection, if applicable.     * @tag@ :/key/ =/value/ - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify @tag:Purpose@ for the filter name and @X@ for the filter value.     * @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.     * @vpc-peering-connection-id@ - The ID of the VPC peering connection.
--
-- * 'dvpcpcVPCPeeringConnectionIds' - One or more VPC peering connection IDs. Default: Describes all your VPC peering connections.
--
-- * 'dvpcpcDryRun' - 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@ .
