Run the task in the provided executor.

same-thread-executor clj/s

schedule! clj/s

(schedule! ms f)

(schedule! scheduler ms f)

(single-pool opts)

A single thread pool constructor.

submit! clj/s

(submit! f)

(submit! executor f)

Submit a task to be executed in a provided executor and return a promise that will be completed with the return value of a task.

A task is a plain clojure function.

thread-factory? clj

(thread-factory? o)

vthreads-supported? clj/s

with-dispatch clj/s macro

(with-dispatch executor & body)

Helper macro for dispatch execution of the body to an executor service. The returned promise is not cancellable (the body will be executed independently of the cancellation).
