textParser :: Monad m => Parser a -> ListT m Text -> ListT (EitherT Error m) a

Given a text parser, produces a transformation of a stream of text chunks into a stream of parsed results. In case of a parsing failure it raises an Error in the EitherT monad over the base.

consumeOne :: Monad m => Parser a -> ListT m Text -> m (Either Error (a, ListT m Text))

Consume only as much input as needed to run the provided parser once. Results in either a failure or the parsed result and the leftover stream. The failure value of Nothing implies the end of input.
