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.
Map a function over all values in the map.
map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
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
Map a function over all values in the map.
map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
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),

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.
