Deserialize any JSON value. Allows atomic values on the top level

eitherDecodeV :: FromJSON a => ByteString -> Either String a

Like decodeV, but returns an error message when decoding fails.

Utilities

fromFloatDigits :: RealFloat a => a -> Scientific

Efficient and exact conversion from a RealFloat into a Scientific number.

(.=?) :: ToJSON a => Text -> Maybe a -> Maybe Pair

Optionally create a Pair.

parseNumber :: Scientific -> Either Integer Double

Convert a Scientific into an Integer if it doesn't have decimal points, otherwise to a Double.
