Apply a transformation to the other computation.
Map both the return value and output of a computation using the given function.
Map both the return value and output of a computation using the given function.
Apply a function to transform the result of a continuation-passing computation.
Apply a function to transform the result of a continuation-passing computation. This has a more restricted type than the map operations for other monad transformers, because ContT does not define a functor in the category of monads.
Map the unwrapped computation using the given function.
Map the unwrapped computation using the given function.
Lift a unary operation to the new monad.
Transform the computation inside a MaybeT.
Map the return value, final state and output of a computation using the given function.
Map the inner computation using the given function.
  • runRWST (mapRWST f m) r s = f (runRWST m r s) mapRWST :: (m (a, s, w) -> n (b, s, w')) -> RWST r w s m a -> RWST r w' s n b
Map the return value, final state and output of a computation using the given function.
Map the inner computation using the given function.
Transform the value returned by a Reader.
Transform the computation inside a ReaderT.
Apply a function to transform the result of a selection computation.
Apply a function to transform the result of a selection computation. This has a more restricted type than the map operations for other monad transformers, because SelectT does not define a functor in the category of monads.
Map both the return value and final state of a computation using the given function.
Map both the return value and final state of a computation using the given function.
Map both the return value and output of a computation using the given function.
Map both the return value and output of a computation using the given function.
Map both the return value and output of a computation using the given function.
Map both the return value and output of a computation using the given function.
