O(n) map f t is the Text obtained by applying f to each element of t. Example:

>>> let message = pack "I am not angry. Not at all."

>>> T.map (\c -> if c == '.' then '!' else c) message
"I am not angry! Not at all!"

Performs replacement on invalid scalar values.

O(n) map f xs is the Stream Char obtained by applying f to each element of xs. Properties

unstream . map f . stream = map f

O(n) map f t is the Text obtained by applying f to each element of t. Performs replacement on invalid scalar values.

O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.

O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.

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"]

Apply a transformation to all values in a stream. Subject to fusion

Apply a transformation to all values in a stream. Subject to fusion Since 0.3.0

Generates a map using a Range to determine the length. This may fail to generate anything if the keys produced by the generator do not account for a large enough number of unique items to satify the required map size.

Apply a function to all values flowing downstream

map id = cat

map (g . f) = map f >-> map g

map f xs is the DList obtained by applying f to each element of xs. <math>(length (toList xs)). map obeys the law:

toList (map f xs) = map f (toList xs)

map f xs is the DNonEmpty obtained by applying f to each element of xs. <math>(length (toNonEmpty xs)). map obeys the law:

toNonEmpty (map f xs) = map f (toNonEmpty xs)

Fold pairs into a map.

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
