Module Resource_throttle

A resource throttle holds a static list of n resources that are handed out in a round-robin fashion to up to n concurrent jobs. A resource given to create may be re-used many times in the lifetime of t but will never be used by more than one job at a time.

type _ t

val kill : _ t -> unit

kills 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 effect currently running jobs in any way.

val is_dead : _ t -> bool

is_dead t returns true if t was killed, either by kill or by an unhandled exception in a job.

val to_limiter : _ t -> limiter
