Creating custom Content Types.

data Content ctypes a Source

class Accept a => Encode a c where Source

Encode a type into a specific content type.

Methods

encode :: Proxy a -> c -> Builder Source

class Accept c => Decode c a where Source

(Try to) Decode a type from a specific content type.

Converting from and to Text

class FromText a where Source

Methods

fromText :: Text -> Maybe a Source

Instances

Methods

toText :: a -> Text Source

Instances

Internal classes.

class Encodings ctypes a where Source

Instances

Encodings ([] *) a Source 
(Accept ctype, Encode ctype a, Encodings ctypes a) => Encodings ((:) * ctype ctypes) a Source 

class Decodings ctypes a where Source
