Sink

valuesinkParser

:: (AttoparsecInput a, MonadThrow m)
=> Parser a b
-> ConduitT a o m b

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

If parsing fails, a ParseError will be thrown with throwM.

Since 0.5.0

valuesinkParserEither

:: (AttoparsecInput a, Monad m)
=> Parser a b
-> ConduitT a o m (Either ParseError b)

Same as sinkParser, but we return an Either type instead of raising an exception.

Since 1.1.5

Conduit

valueconduitParser

:: (AttoparsecInput a, MonadThrow m)
=> Parser a b
-> ConduitT a (PositionRange, b) m ()

Consume a stream of parsed tokens, returning both the token and the position it appears at. This function will raise a ParseError on bad input.

Since 0.5.0

valueconduitParserEither

:: (Monad m, AttoparsecInput a)
=> Parser a b
-> ConduitT a (Either ParseError (PositionRange, b)) m ()

Same as conduitParser, but we return an Either type instead of raising an exception.
