Synopsis

data UnexpectedDecodeEx where Source #

Type safety over encodings makes decoding process safe. However failures are still possible due to bugs or unsafe payload modifications. UnexpectedDecodeEx represents such errors.

Constructors

UnexpectedDecodeEx :: (Show a, KnownSymbol x) => Proxy x -> a -> UnexpectedDecodeEx 
Instances
Show UnexpectedDecodeEx Source # 
Instance details

Defined in Data.TypedEncoding.Internal.Types

Methods

showsPrec :: Int -> UnexpectedDecodeEx -> ShowS #

show :: UnexpectedDecodeEx -> String #

showList :: [UnexpectedDecodeEx] -> ShowS #

UnexpectedDecodeErr (Either UnexpectedDecodeEx) Source # 
Instance details

Defined in Data.TypedEncoding.Internal.Class.Decode

Methods

unexpectedDecodeErr :: UnexpectedDecodeEx -> Either UnexpectedDecodeEx a Source #

data EncodeEx where Source #

Represents errors in encoding

Constructors

EncodeEx :: (Show a, KnownSymbol x) => Proxy x -> a -> EncodeEx 
Instances
Show EncodeEx Source #

Defined in Data.TypedEncoding.Internal.Types

Methods

showsPrec :: Int -> EncodeEx -> ShowS #

show :: EncodeEx -> String #

showList :: [EncodeEx] -> ShowS #

EncodeF (Either EncodeEx) (Enc xs c ByteString) (Enc ("r-UTF8" ': xs) c ByteString :: Type) Source # 
Instance details

Defined in Data.TypedEncoding.Instances.Restriction.UTF8

Methods

encodeF :: Enc xs c ByteString -> Either EncodeEx (Enc ("r-UTF8" ': xs) c ByteString) Source #

EncodeF (Either EncodeEx) (Enc xs c ByteString) (Enc ("r-UTF8" ': xs) c ByteString :: Type) Source #

UTF8 encodings are defined for ByteString only as that would not make much sense for Text

>>> encodeFAll . toEncoding () $ "\xc3\xb1" :: Either EncodeEx (Enc '["r-UTF8"] () B.ByteString)
Right (MkEnc Proxy () "\195\177")
>>> encodeFAll . toEncoding () $ "\xc3\x28" :: Either EncodeEx (Enc '["r-UTF8"] () B.ByteString)
Left (EncodeEx "r-UTF8" (Cannot decode byte '\xc3': Data.Text.Internal.Encoding.decodeUtf8: Invalid UTF-8 stream))

Following test uses verEncoding helper that checks that bytes are encoded as Right iff they are valid UTF8 bytes

\(b :: B.ByteString) -> verEncoding b (fmap (fromEncoding . decodeAll . proxiedId (Proxy :: Proxy (Enc '["r-UTF8"] _ _))) . (encodeFAll :: _ -> Either EncodeEx _). toEncoding () $ b)
