## LogosDeliveryInterface — the facade / mainClass interface.
##
## Owns the node and the three sub-interfaces; getters return them. This module
## imports AND re-exports the three sub-interface contracts so a consumer can
## `import ./LogosDeliveryInterface` and get the whole interface surface.

import results, chronos
import brokers/broker_interface

# Module aliases avoid the module-name vs type-name clash (file KernelInterface.nim
# exports type KernelInterface); the type names stay in scope unqualified for the getters.
import ./kernel_interface as ikernel_iface
import ./messaging_client_interface as imessagingclient_iface
import ./reliable_channel_manager_interface as ireliablechannelmanager_iface
