  1. mapM :: (Monad m, Unbox a, Unbox b) => (a -> m b) -> Vector a -> m (Vector b)

    rebase Rebase.Data.Vector.Unboxed

    No documentation available.

  2. mapM_ :: (Monad m, Unbox a) => (a -> m b) -> Vector a -> m ()

    rebase Rebase.Data.Vector.Unboxed

    No documentation available.

  3. mapMaybe :: (Unbox a, Unbox b) => (a -> Maybe b) -> Vector a -> Vector b

    rebase Rebase.Data.Vector.Unboxed

    No documentation available.

  4. mapMaybeM :: (Monad m, Unbox a, Unbox b) => (a -> m (Maybe b)) -> Vector a -> m (Vector b)

    rebase Rebase.Data.Vector.Unboxed

    No documentation available.

  5. mapM_ :: (PrimMonad m, Unbox a) => (a -> m b) -> MVector (PrimState m) a -> m ()

    rebase Rebase.Data.Vector.Unboxed.Mutable

    No documentation available.

  6. mapBoth :: (a -> c) -> (b -> d) -> Either a b -> Either c d

    rebase Rebase.Prelude

    The mapBoth function takes two functions and applies the first if iff the value takes the form Left _ and the second if the value takes the form Right _. Using Data.Bifunctor:

    mapBoth = bimap
    
    Using Control.Arrow:
    mapBoth = (+++)
    
    >>> mapBoth (*2) (*3) (Left 4)
    Left 8
    
    >>> mapBoth (*2) (*3) (Right 4)
    Right 12
    

  7. mapCont :: (r -> r) -> Cont r a -> Cont r a

    rebase Rebase.Prelude

    Apply a function to transform the result of a continuation-passing computation.

  8. mapExcept :: (Either e a -> Either e' b) -> Except e a -> Except e' b

    rebase Rebase.Prelude

    Map the unwrapped computation using the given function.

  9. mapExceptT :: (m (Either e a) -> n (Either e' b)) -> ExceptT e m a -> ExceptT e' n b

    rebase Rebase.Prelude

    Map the unwrapped computation using the given function.

  10. mapMaybeT :: (m (Maybe a) -> n (Maybe b)) -> MaybeT m a -> MaybeT n b

    rebase Rebase.Prelude

    Transform the computation inside a MaybeT.
