import Network.HTTP.Link
import Network.URI
import Data.Maybe

                , Link (fromJust $ parseURI "https://yolo.tld") [(Rel, "license")] ]
-- "<https://example.com/hello%20world>; rel=\"next\"; title=\"hello world\", <https://yolo.tld>; rel=\"license\""

----- Parsing
parseLinkHeader "<https://example.com/2>; rel=\"next\", <https://example.com/0>; rel=prev"
-- Just [ Link https://example.com/2 [(Rel, "next")]
--      , Link https://example.com/0 [(Rel, "prev")] ]
