Control.Eff.Coroutine

Coroutines implemented with extensible effects

Synopsis

datadata Yield a (b :: k) (v :: k) where

Co-routines The interface is intentionally chosen to be the same as in transf.hs

| The yield request: reporting a value of type e and suspending the coroutine. Resuming with the value of type b

Instances1Handle

Handle (Yield a b) (Yield a b ': r) w (Eff r (Y r b a))Defined in extensible-effects-5.0.0.1 · Control.Eff.Coroutine
Given a continuation and a request, respond to it

valuewithCoroutine :: Monad m => b -> m (Y r w a)

Return a pure value

valueyield :: Member (Yield a b) r => a -> Eff r b

Yield a value of type a and suspend the coroutine.

valuerunC :: Eff (Yield a b ': r) w -> Eff r (Y r b a)

Launch a thread and report its status

datadata Y (r :: [Type -> Type]) w a

Status of a thread: done or reporting the value of the type a (For simplicity, a co-routine reports a value but accepts unit)

Type parameter r is the effect we're yielding from.

Type parameter a is the type that is yielded.

Type parameter w is the type of the value returned from the coroutine when it has completed.
