Documentation
buffer :: Text -> Buffer Source #
The initial Buffer has no mutable zone, so we can avoid all
 copies in the (hopefully) common case of no further input being fed
 to us.
iter :: Buffer -> Int -> Iter Source #
O(1) Iterate (unsafely) one step forwards through a UTF-16 array, returning the current character and the delta to add to give the next offset to iterate at.
iter_ :: Buffer -> Int -> Int Source #
O(1) Iterate one step through a UTF-16 array, returning the delta to add to give the next offset to iterate at.
lengthCodeUnits :: Text -> Int Source #
