-- Data types

-- | 'Hints' represent a collection of 'ErrorItem's to be included into
-- 'ParseError' (when it's a 'TrivialError') as “expected” message items
-- when a parser fails without consuming input right after successful parser
-- that produced the hints.
--
-- For example, without hints you could get:
--
-- >>> parseTest (many (char 'r') <* eof) "ra"
-- 1:2:
-- unexpected 'a'
-- expecting end of input
--
-- We're getting better error messages with the help of hints:
--
-- >>> parseTest (many (char 'r') <* eof) "ra"
-- 1:2:
-- unexpected 'a'
-- expecting 'r' or end of input

-- __Note__ that the inner parser will start with an empty collection of
-- “delayed” 'ParseError's. Any delayed 'ParseError's produced in the inner
-- parser will be lifted by applying the provided function and added to the
-- collection of delayed parse errors of the outer parser.
