O(n) Map a function over a vector.

Map a function over a Bundle

Map a function over a Bundle

O(n) Map a function over a vector.

O(n) Map a function over a vector.

O(n) Map a function over a vector.

O(n) Map a function over a vector.

Transform this map by applying a function to every value.

Transform this set by applying a function to every value. The resulting set may be smaller than the source.

>>> HashSet.map show (HashSet.fromList [1,2,3])
HashSet.fromList ["1","2","3"]

Transform the original string-like value but keep it case insensitive.

Apply a function to each element of a Stream, lazily

map f xs is the list obtained by applying f to each element of xs, i.e.,

map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
map f [x1, x2, ...] == [f x1, f x2, ...]

>>> map (+1) [1, 2, 3]
[2,3,4]

Apply a transformation to the other computation.

Map both the return value and output of a computation using the given function.

• runAccum (mapAccum f m) = f . runAccum
  m

Map both the return value and output of a computation using the given function.

• runAccumT (mapAccumT f m) = f .
  runAccumT m

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

• runCont (mapCont f m) = f . runCont
  m

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.

• runContT (mapContT f m) = f . runContT
  m

Map the unwrapped computation using the given function.

• runExcept (mapExcept f m) = f (runExcept
  m)

Map the unwrapped computation using the given function.

• runExceptT (mapExceptT f m) = f
  (runExceptT m)

Lift a unary operation to the new monad.

Transform the computation inside a MaybeT.

• runMaybeT (mapMaybeT f m) = f (runMaybeT
  m)

Map the return value, final state and output of a computation using the given function.

• runRWS (mapRWS f m) r s = f (runRWS m r
  s)
