Map a function over all values in the map.
O(n) map f xs is the ByteString obtained by
applying
f to each element of
xs.
O(n) map f xs is the ByteString 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.
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 t is the
Text
obtained by applying
f to each element of
t.
Performs replacement on invalid scalar values.
Apply a function to each element, returning any other valid
ListLike.
rigidMap will always be at least as fast, if
not faster, than this function and is recommended if it will work for
your purposes. See also
mapM.
Apply a function uniformly over all elements of a sequence.
Map all element a from a block to a new block of b
Map all elements in a list
O(n*log n) Map a function over all the left keys in the map.
Version 0.3
Combinator for the
<map> element.
Example:
map $ span $ toHtml "foo"
Result:
<map><span>foo</span></map>
Map over bytes in a sequence. The result has the same length as the
argument.
Transform the original string-like value but keep it case insensitive.
