Module Callbacks.DummySource
Dummy callbacks. It can be useful to reuse some of these functions in a real subscriber that doesn't want to handle all events, but only some of them.
To write a subscriber that only supports some callbacks, this can be handy:
module My_callbacks = struct
type st = my_own_state
include Callbacks.Dummy
let on_counter (st:st) ~time_ns ~tid ~data ~name v : unit = ...
