Jordan.FromJSON.Attoparsec

Implementation of FromJSON parsers via Attoparsec.

This module does not construct intermediate data structures like maps or key-value lists, and instead uses permutation parsers in order to parse your data structure directly. This means that it is pretty fast! However, you also get basically *zero* error reporting, which is generally not what you want.

parseViaAttoparsecWith :: (forall parser. JSONParser parser => parser a) -> ByteString -> Either String a

parseViaAttoparsec :: forall val. FromJSON val => ByteString -> Either String val
