-- | One or more filters.
--
-- -   'accepter-vpc-info.cidr-block' - The 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 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.
