(require (planet jaymccarthy/job-queue))

(job-queue? v) → boolean?

how-many-workers : exact-nonnegative-integer?

Starts a queue with how-many-workers threads servicing jobs.

(submit-job! jq job) → void

jq : job-queue?

job : (-> any)

Runs job by one of jq’s workers. job is run in the same parameterization as the call to submit-job!. This call will never block.

(stop-job-queue! jq) → void

jq : job-queue?

Blocks until all of jq’s current jobs are finished and its workers are dead. Once stop-job-queue! has been called, jq will reject subsequent requests and submit-job! will block indefinitely.
