  1. map :: Functor f => (a -> b) -> f a -> f b

    classy-prelude ClassyPrelude

    No documentation available.

  2. map :: forall (m :: Type -> Type) a b x . Monad m => (a -> b) -> Stream m a x -> Stream m b x

    ghc-lib-parser GHC.Data.Stream

    Apply a function to each element of a Stream, lazily

  3. map :: (a -> b) -> Word64Map a -> Word64Map b

    ghc-lib-parser GHC.Data.Word64Map.Internal

    Map a function over all values in the map.

    map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
    

  4. map :: (a -> b) -> Word64Map a -> Word64Map b

    ghc-lib-parser GHC.Data.Word64Map.Lazy

    Map a function over all values in the map.

    map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
    

  5. map :: (a -> b) -> Word64Map a -> Word64Map b

    ghc-lib-parser GHC.Data.Word64Map.Strict

    Map a function over all values in the map.

    map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
    

  6. map :: (a -> b) -> Word64Map a -> Word64Map b

    ghc-lib-parser GHC.Data.Word64Map.Strict.Internal

    Map a function over all values in the map.

    map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
    

  7. map :: (Key -> Key) -> Word64Set -> Word64Set

    ghc-lib-parser GHC.Data.Word64Set

    map f s is the set obtained by applying f to each element of s. It's worth noting that the size of the result may be smaller if, for some (x,y), x /= y && f x == f y

  8. map :: (Key -> Key) -> Word64Set -> Word64Set

    ghc-lib-parser GHC.Data.Word64Set.Internal

    map f s is the set obtained by applying f to each element of s. It's worth noting that the size of the result may be smaller if, for some (x,y), x /= y && f x == f y

  9. map :: (a -> b) -> [a] -> [b]

    ghc-lib-parser GHC.Prelude.Basic

    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, ...]
    
    this means that map id == id

    Examples

    >>> map (+1) [1, 2, 3]
    [2,3,4]
    
    >>> map id [1, 2, 3]
    [1,2,3]
    
    >>> map (\n -> 3 * n + 1) [1, 2, 3]
    [4,7,10]
    

  10. map :: Ord b => (a -> b) -> MaxQueue a -> MaxQueue b

    pqueue Data.PQueue.Max

    Creates a new priority queue containing the images of the elements of this queue. Equivalent to fromList . map f . toList.
