module Data.Encoding.Exception

module Data.Encoding.ByteSource

module Data.Encoding.ByteSink

class Encoding enc where

The base class for all encodings. At least decodeChar, encodeChar and encodeable must be implemented.

Minimal complete definition

decodeChar, encodeChar, encodeable

Methods

decodeChar :: ByteSource m => enc -> m Char

Read a single character of a ByteSource

encodeChar :: ByteSink m => enc -> Char -> m ()

Encode a single character and write it to a ByteSink

decode :: ByteSource m => enc -> m String

Read characters from a ByteSource until it is empty

encode :: ByteSink m => enc -> String -> m ()

Encode a String and write it to a ByteSink

encodeable :: enc -> Char -> Bool

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.
