  1. mapping :: forall (f :: Type -> Type) (g :: Type -> Type) s t a b . (Functor f, Functor g) => AnIso s t a b -> Iso (f s) (g t) (f a) (g b)

    gogol-core Gogol.Prelude

    This can be used to lift any Iso into an arbitrary Functor.

  2. mapConcurrently :: (MonadUnliftIO m, Traversable t) => (a -> m b) -> t a -> m (t b)

    unliftio UnliftIO.Async

    Executes a Traversable container of items concurrently, it uses the Flat type internally.

  3. mapConcurrently_ :: (MonadUnliftIO m, Foldable f) => (a -> m b) -> f a -> m ()

    unliftio UnliftIO.Async

    Executes a Traversable container of items concurrently, it uses the Flat type internally. This function ignores the results.

  4. mapExceptionM :: (Exception e1, Exception e2, MonadUnliftIO m) => (e1 -> e2) -> m a -> m a

    unliftio UnliftIO.Exception

    Same as mapException, except works in a monadic context.

  5. mapConcurrently :: (MonadUnliftIO m, Traversable t) => (a -> m b) -> t a -> m (t b)

    unliftio UnliftIO.Internals.Async

    Executes a Traversable container of items concurrently, it uses the Flat type internally.

  6. mapConcurrently_ :: (MonadUnliftIO m, Foldable f) => (a -> m b) -> f a -> m ()

    unliftio UnliftIO.Internals.Async

    Executes a Traversable container of items concurrently, it uses the Flat type internally. This function ignores the results.

  7. mapMaybe :: (MonadGen m, GenBase m ~ Identity) => (a -> Maybe b) -> m a -> m b

    hedgehog Hedgehog.Gen

    Generates a value which is the result of the given function returning a Just. The original generator's shrink tree will be retained, with values returning Nothing removed. Subsequent shrinks of those values will be retained. Compared to mapMaybeT, shrinking may be slower but will be optimal. It's possible that the function will never return Just, or will only do so a larger size than we're currently running at. To avoid looping forever, we limit the number of retries, and grow the size with each retry. If we retry too many times then the whole generator is discarded.

  8. mapMaybeT :: MonadGen m => (a -> Maybe b) -> m a -> m b

    hedgehog Hedgehog.Gen

    Generates a value which is the result of the given function returning a Just. The original generator's shrink tree will be retained, with values returning Nothing removed. Subsequent shrinks of those values will be retained. Compared to mapMaybeT, shrinking may be slower but will be optimal. The type is also more general, because the shrink behavior from mapMaybe would force the entire shrink tree to be evaluated when applied to an impure tree. It's possible that the function will never return Just, or will only do so a larger size than we're currently running at. To avoid looping forever, we limit the number of retries, and grow the size with each retry. If we retry too many times then the whole generator is discarded.

  9. mapGenT :: forall (m :: Type -> Type) a (n :: Type -> Type) b . (TreeT (MaybeT m) a -> TreeT (MaybeT n) b) -> GenT m a -> GenT n b

    hedgehog Hedgehog.Internal.Gen

    Map over a generator's shrink tree.

  10. mapMaybe :: (MonadGen m, GenBase m ~ Identity) => (a -> Maybe b) -> m a -> m b

    hedgehog Hedgehog.Internal.Gen

    Generates a value which is the result of the given function returning a Just. The original generator's shrink tree will be retained, with values returning Nothing removed. Subsequent shrinks of those values will be retained. Compared to mapMaybeT, shrinking may be slower but will be optimal. It's possible that the function will never return Just, or will only do so a larger size than we're currently running at. To avoid looping forever, we limit the number of retries, and grow the size with each retry. If we retry too many times then the whole generator is discarded.
