-- | One or more filters.
--
-- -   'is-classic-link-enabled' - Whether the VPC is enabled for
--     ClassicLink ('true' | 'false').
--
-- -   '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.
