-- | 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 peer VPC.     * @accepter-vpc-info.owner-id@ - The AWS account ID of the owner of the peer VPC.     * @accepter-vpc-info.vpc-id@ - The ID of the peer 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@ | @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.     * @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@ .
