Data.ByteString.Base16.Lazy
Description
RFC 4648-compliant Base16 (Hexadecimal) encoding for lazy ByteString values.
For a complete Base16 encoding specification, please see RFC-4648 section 8.
Synopsis
- encode :: ByteString -> ByteString
- decode :: ByteString -> Either String ByteString
- decodeLenient :: ByteString -> ByteString
Documentation
encode :: ByteString -> ByteString Source #
Encode a ByteString value in base16 (i.e. hexadecimal).
Encoded values will always have a length that is a multiple of 2.
Examples:
encode "foo" == "666f6f"
decode :: ByteString -> Either String ByteString Source #
Decode a base16-encoded ByteString value.
If errors are encountered during the decoding process,
then an error message and character offset will be returned in
the Left clause of the coproduct.
Examples:
decode "666f6f" == Right "foo" decode "66quux" == Left "invalid character at offset: 2" decode "666quu" == Left "invalid character at offset: 3"
Since: 1.0.0.0
decodeLenient :: ByteString -> ByteString Source #
Decode a Base16-encoded ByteString value leniently, using a
strategy that never fails.
N.B.: this is not RFC 4648-compliant
Examples:
decodeLenient "666f6f" == "foo" decodeLenient "66quux" == "f" decodeLenient "666quu" == "f" decodeLenient "666fqu" == "fo"
Since: 1.0.0.0
