yield package:monad-coroutine

yield :: Monad m => x -> Coroutine (Yield x) m ()
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
Suspend the current coroutine yielding a value.
data Yield x y
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
The Yield functor instance is equivalent to (,) but more descriptive. A coroutine with this suspension functor provides a value with every suspension.
Yield :: x -> y -> Yield x y
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
concatYields :: (Monad m, Foldable f) => Coroutine (Yield (f x)) m r -> Coroutine (Yield x) m r
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
Converts a coroutine yielding collections of values into one yielding single values.
weaveAwaitMaybeYield :: Monad m => WeaveStepper (Await (Maybe x)) (Yield x) Identity m r1 r2 (r1, r2)
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
Like weaveAwaitYield, except the Await coroutine expects Maybe-wrapped values. After the Yield coroutine terminates, the Await coroutine receives only Nothing.
weaveAwaitYield :: Monad m => x -> WeaveStepper (Await x) (Yield x) Identity m r1 r2 (r1, r2)
monad-coroutine Control.Monad.Coroutine.SuspensionFunctors
Weaves the suspensions of a Yield and an Await coroutine together into a plain Identity coroutine. If the Yield coroutine terminates first, the Await one is resumed using the argument default value.
