-- Lists the associations between your Direct Connect gateways and virtual
-- private gateways and transit gateways. You must specify one of the
-- following:
--
-- -   A Direct Connect gateway
--
--     The response contains all virtual private gateways and transit
--     gateways associated with the Direct Connect gateway.
--
-- -   A virtual private gateway
--
--     The response contains the Direct Connect gateway.
--
-- -   A transit gateway
--
--     The response contains the Direct Connect gateway.
--
-- -   A Direct Connect gateway and a virtual private gateway
--
--     The response contains the association between the Direct Connect
--     gateway and virtual private gateway.
--
-- -   A Direct Connect gateway and a transit gateway
--
--     The response contains the association between the Direct Connect
--     gateway and transit gateway.
--
-- This operation returns paginated results.
