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-8 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-8 array, returning the delta to add to give the next offset to iterate at.
