map :: (a -> b) -> InputStream a -> IO (InputStream b)io-streams System.IO.Streams.Combinators Maps a pure function over an InputStream. map f s passes all output from s through the function f. Satisfies the following laws:
Streams.map (g . f) === Streams.map f >=> Streams.map g Streams.map id === Streams.makeInputStream . Streams.read
map :: (v1 -> v2) -> KeyMap v1 -> KeyMap v2autodocodec Autodocodec.Aeson.Compat No documentation available.
map :: (Word8 -> Word8) -> ByteString -> ByteStringrio RIO.ByteString O(n) map f xs is the ByteString obtained by applying f to each element of xs.
map :: (Word8 -> Word8) -> ByteString -> ByteStringrio RIO.ByteString.Lazy O(n) map f xs is the ByteString obtained by applying f to each element of xs.
map :: (v1 -> v2) -> HashMap k v1 -> HashMap k v2rio RIO.HashMap Transform this map by applying a function to every value.
map :: (Hashable b, Eq b) => (a -> b) -> HashSet a -> HashSet brio RIO.HashSet Transform this set by applying a function to every value. The resulting set may be smaller than the source.

rio RIO.List 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 == idExamples
>>> 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]
map :: (a -> b) -> Map k a -> Map k brio RIO.Map Map a function over all values in the map.
map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
map :: (a -> b) -> NonEmpty a -> NonEmpty brio RIO.NonEmpty Map a function over a NonEmpty stream.
