Control.Eff.Coroutine

Coroutines implemented with extensible effects

Documentation

data Yield a v

The yield request: reporting a value of type e and suspending the coroutine. For readability, a coroutine accepts a unit to produce its value.

Constructors

Yield a (() -> v)

Instances

Functor (Yield a)

Methods

fmap :: (a -> b) -> Yield a a -> Yield a b

(<$) :: a -> Yield a b -> Yield a a

yield :: (Typeable a, Member (Yield a) r) => a -> Eff r ()

Yield a value of type a and suspend the coroutine.

runC :: Typeable a => Eff (Yield a :> r) w -> Eff r (Y r a w)

Launch a thread and report its status.

data Y r a w

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.

Constructors

Y a (() -> Eff r (Y r a w))

Done w
