decode package:aeson

decode :: FromJSON a => ByteString -> Maybe a
aeson Data.Aeson Data.Aeson.Decoding
Efficiently deserialize a JSON value from a lazy ByteString. If this fails due to incomplete or invalid input, Nothing is returned.
decode' :: FromJSON a => ByteString -> Maybe a
aeson Data.Aeson
Efficiently deserialize a JSON value from a lazy ByteString. If this fails due to incomplete or invalid input, Nothing is returned. Since 2.2.0.0 an alias for decode.
decodeFileStrict :: FromJSON a => FilePath -> IO (Maybe a)
aeson Data.Aeson
Efficiently deserialize a JSON value from a file. If this fails due to incomplete or invalid input, Nothing is returned. The input file's content must consist solely of a JSON document, with no trailing data except for whitespace. This function parses immediately, but defers conversion. See json for details.
decodeFileStrict' :: FromJSON a => FilePath -> IO (Maybe a)
aeson Data.Aeson
Efficiently deserialize a JSON value from a file. If this fails due to incomplete or invalid input, Nothing is returned. Since 2.2.0.0 an alias for decodeFileStrict.
decodeStrict :: FromJSON a => ByteString -> Maybe a
aeson Data.Aeson Data.Aeson.Decoding
Efficiently deserialize a JSON value from a strict ByteString. If this fails due to incomplete or invalid input, Nothing is returned.
decodeStrict' :: FromJSON a => ByteString -> Maybe a
aeson Data.Aeson
Efficiently deserialize a JSON value from a strict ByteString. If this fails due to incomplete or invalid input, Nothing is returned. Since 2.2.0.0 an alias for decodeStrict.
decodeStrictText :: FromJSON a => Text -> Maybe a
aeson Data.Aeson Data.Aeson.Decoding
Efficiently deserialize a JSON value from a strict Text. If this fails due to incomplete or invalid input, Nothing is returned.
eitherDecode :: FromJSON a => ByteString -> Either String a
aeson Data.Aeson Data.Aeson.Decoding
Like decode but returns an error message when decoding fails.
eitherDecode' :: FromJSON a => ByteString -> Either String a
aeson Data.Aeson
Like decode' but returns an error message when decoding fails. Since 2.2.0.0 an alias for eitherDecode.
eitherDecodeFileStrict :: FromJSON a => FilePath -> IO (Either String a)
aeson Data.Aeson
Like decodeFileStrict but returns an error message when decoding fails.
eitherDecodeFileStrict' :: FromJSON a => FilePath -> IO (Either String a)
aeson Data.Aeson
Like decodeFileStrict' but returns an error message when decoding fails. Since 2.2.0.0 an alias for eitherDecodeFileStrict'.
eitherDecodeStrict :: FromJSON a => ByteString -> Either String a
aeson Data.Aeson Data.Aeson.Decoding
Like decodeStrict but returns an error message when decoding fails.
eitherDecodeStrict' :: FromJSON a => ByteString -> Either String a
aeson Data.Aeson
Like decodeStrict' but returns an error message when decoding fails. Since 2.2.0.0 an alias for eitherDecodeStrict.
eitherDecodeStrictText :: FromJSON a => Text -> Either String a
aeson Data.Aeson Data.Aeson.Decoding
Like decodeStrictText but returns an error message when decoding fails.
throwDecode :: forall a m . (FromJSON a, MonadThrow m) => ByteString -> m a
aeson Data.Aeson Data.Aeson.Decoding
Like decode but throws an AesonException when decoding fails. throwDecode is in aeson since 2.1.2.0, but this variant is added later.
throwDecode' :: forall a m . (FromJSON a, MonadThrow m) => ByteString -> m a
aeson Data.Aeson
Like decode' but throws an AesonException when decoding fails. Since 2.2.0.0 an alias for throwDecode.
throwDecodeStrict :: forall a m . (FromJSON a, MonadThrow m) => ByteString -> m a
aeson Data.Aeson Data.Aeson.Decoding
Like decodeStrict but throws an AesonException when decoding fails.
throwDecodeStrict' :: forall a m . (FromJSON a, MonadThrow m) => ByteString -> m a
aeson Data.Aeson
Like decodeStrict' but throws an AesonException when decoding fails. Since 2.2.0.0 an alias for throwDecodeStrict.
throwDecodeStrictText :: forall a m . (FromJSON a, MonadThrow m) => Text -> m a
aeson Data.Aeson Data.Aeson.Decoding
Like decodeStrictText but throws an AesonException when decoding fails.
