takeWhile :: (Char -> Bool) -> Text -> Text
text Data.Text Data.Text.Lazy
O(n) takeWhile, applied to a predicate p and a Text, returns the longest prefix (possibly empty) of elements that satisfy p.
takeWhile :: (Char -> Bool) -> Stream Char -> Stream Char
text Data.Text.Internal.Fusion.Common
takeWhile, applied to a predicate p and a stream, returns the longest prefix (possibly empty) of elements that satisfy p. Properties 
unstream . takeWhile p . stream = takeWhile p
takeWhileEnd :: (Char -> Bool) -> Text -> Text
text Data.Text
O(n) takeWhileEnd, applied to a predicate p and a Text, returns the longest suffix (possibly empty) of elements that satisfy p. Examples: 
>>> takeWhileEnd (=='o') "foo"
"oo"
takeWhileEnd :: (Char -> Bool) -> Text -> Text
text Data.Text.Lazy
O(n) takeWhileEnd, applied to a predicate p and a Text, returns the longest suffix (possibly empty) of elements that satisfy p. Examples: 
takeWhileEnd (=='o') "foo" == "oo"
