Backend (eio.Eio_mock.Backend)

exception Deadlock_detected

val run : (unit -> 'a) -> 'a

run fn runs an event loop and then calls fn env within it.

raises Deadlock_detected
if the run queue becomes empty but fn hasn't returned.

type stdenv =
  < clock : Clock.t
  ; mono_clock : Clock.Mono.t
  ; debug : Eio.Debug.t
  ; backend_id : string >

val run_full : (stdenv -> 'a) -> 'a

run_full is like run but also provides a mock environment.

The mock monotonic clock it provides advances automatically when there is nothing left to do. The mock wall clock is linked directly to the monotonic time.
