Limiter_async.SequencerSourceA sequencer is a throttle that is specialized to only allow one job at a time and to, by default, not continue on error.
val enqueue' :
t ->
('a -> 'b Async_kernel.Deferred.t) ->
'a ->
'b Outcome.t Async_kernel.Deferred.tinclude Common with type 'a t := 'a ukills t, which aborts all enqueued jobs that haven't started and all jobs enqueued in the future. If t has already been killed, then calling kill t has no effect. Note that kill does not affect currently running jobs in any way.
is_dead t returns true if t was killed, either by kill or by an unhandled exception in a job.
