-- | 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.
