Module `Eio_mock.Backend`Source

A dummy Eio backend with no actual IO.

This backend does not support the use of multiple domains or systhreads, but the tradeoff is that it can reliably detect deadlock, because if the run queue is empty then it knows that no wake up event can be coming from elsewhere.

Sourceexception Deadlock_detected

Sourceval 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 >

Sourceval 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.
