Documentation
module Data.Encoding.Exception
module Data.Encoding.ByteSource
module Data.Encoding.ByteSink
class Encoding enc whereSource
The base class for all encodings. At least decodeChar, encodeChar and encodeable must be implemented.
Methods
decodeChar :: ByteSource m => enc -> m CharSource
Read a single character of a ByteSource
encodeChar :: ByteSink m => enc -> Char -> m ()Source
Encode a single character and write it to a ByteSink
decode :: ByteSource m => enc -> m StringSource
Read characters from a ByteSource until it is empty
encode :: ByteSink m => enc -> String -> m ()Source
Encode a String and write it to a ByteSink
encodeable :: enc -> Char -> BoolSource
Tests whether a given character is representable in the Encoding. If this yields True, encodeChar must not fail. If it yields False, encodeChar _must_ throw an exception.
Instances
data DynEncoding Source
Wraps all possible encoding types into one data type. Used when a function needs to return an encoding.
Instances
encodeString :: Encoding enc => enc -> String -> StringSource
encodeStringExplicit :: Encoding enc => enc -> String -> Either EncodingException StringSource
decodeString :: Encoding enc => enc -> String -> StringSource
decodeStringExplicit :: Encoding enc => enc -> String -> Either DecodingException StringSource
encodeLazyByteString :: Encoding enc => enc -> String -> ByteStringSource
encodeLazyByteStringExplicit :: Encoding enc => enc -> String -> Either EncodingException ByteStringSource
decodeLazyByteString :: Encoding enc => enc -> ByteString -> StringSource
decodeLazyByteStringExplicit :: Encoding enc => enc -> ByteString -> Either DecodingException StringSource
encodeStrictByteString :: Encoding enc => enc -> String -> ByteStringSource
encodeStrictByteStringExplicit :: Encoding enc => enc -> String -> Either EncodingException ByteStringSource
decodeStrictByteString :: Encoding enc => enc -> ByteString -> StringSource
decodeStrictByteStringExplicit :: Encoding enc => enc -> ByteString -> Either DecodingException StringSource
encodingFromString :: String -> DynEncodingSource
Takes the name of an encoding and creates a dynamic encoding from it.
encodingFromStringExplicit :: String -> Maybe DynEncodingSource
Like encodingFromString but returns Nothing instead of throwing an error
