Module `Async_kernel__.Job_or_event_intf`

Job_or_event is a custom zero-alloc sum type that is like:

| Event of Event.t
| Job   of Job.t

except that it uses the fact that Event.t is a pointer and Job.t is an int to be zero alloc.

module Event = Async_kernel__.Types.Event

module type Job_or_event = sig ... end
