Instances

AttoparsecInput ByteString #
Methods parseA :: Parser ByteString b -> ByteString -> IResult ByteString b feedA :: IResult ByteString b -> ByteString -> IResult ByteString b empty :: ByteString isNull :: ByteString -> Bool notEmpty :: [ByteString] -> [ByteString]
AttoparsecInput Text #
Methods parseA :: Parser Text b -> Text -> IResult Text b feedA :: IResult Text b -> Text -> IResult Text b empty :: Text isNull :: Text -> Bool notEmpty :: [Text] -> [Text]

iterParser :: (AttoparsecInput a, Monad m) => Parser a b -> Iteratee a m b #

Convert an Attoparsec Parser into an Iteratee. The parser will be streamed bytes until it returns Done or Fail.

If parsing fails, a ParseError will be thrown with throwError. Use catchError to catch it.
