ei_callback
Callback Object
Interface for ensuring a roundtrip to the EIS implementation.
Clients can handle the ‘done’ event to get notified when
the related request that created the ei_callback object is done.
Note that for a client to receive objects of this type, it must announce
support for this interface in ei_handshake.interface_version.

Notify the client when the related request is done. Immediately after this event
