Documentation
decode :: FromJSON a => ByteString -> Maybe a Source #
Efficiently deserialize a JSON value from a strict ByteString.
If this fails due to incomplete or invalid input, Nothing is
returned.
eitherDecode :: FromJSON a => ByteString -> Either String a Source #
Like decodeStrict but returns an error message when decoding fails.
throwDecode :: forall a m. (FromJSON a, MonadThrow m) => ByteString -> m a Source #
Like decode but throws an AesonException when decoding fails.
decodeStrict :: FromJSON a => ByteString -> Maybe a Source #
Efficiently deserialize a JSON value from a strict ByteString.
If this fails due to incomplete or invalid input, Nothing is
returned.
eitherDecodeStrict :: FromJSON a => ByteString -> Either String a Source #
Like decodeStrict but returns an error message when decoding fails.
throwDecodeStrict :: forall a m. (FromJSON a, MonadThrow m) => ByteString -> m a Source #
Like decodeStrict but throws an AesonException when decoding fails.
