This module contains Text-valued combinators for implementing the RFC 4648 specification of the Base16 encoding format. This includes lenient decoding variants, as well as internal and external validation for canonicity.
Encode a lazy Text value in Base16 with padding.
See: RFC-4648 section 8
encodeBase16 "Sun""53756e"
Decode a Base16-encoded lazy Text value.
See: RFC-4648 section 8
decodeBase16 $ assertBase16 "53756e""Sun"
Decode an untyped Base16-encoded lazy Text value.
See: RFC-4648 section 8

decodeBase16With :: (ByteString -> Either err Text)convert a bytestring to text (e.g. T.decodeUtf8')
-> ByteStringInput to decode
-> Either (Base16Error err) TextAttempt to decode an untyped lazy Text value as Base16, converting from ByteString to Text according to some encoding function. In practice, This is something like decodeUtf8', which may produce an error.
See: RFC-4648 section 8
decodeBase16With decodeUtf8'
:: ByteString -> Either (Base16Error UnicodeException) Text
Decode a Base16-encoded lazy Text value leniently, using a strategy that never fails.
Warning: in the conversion to unicode text, exceptions may be thrown.
Please use decodeBase16' if you are unsure if you are working with
base16-encoded values, or if you expect garbage.
N.B.: this is not RFC 4648-compliant. It may give you garbage if you're not careful!

Tell whether a lazy Text value is Base16-encoded.
isBase16 "666f6"False
isBase16 "666f"True
Tell whether a lazy Text value is a valid Base16 format.
This will not tell you whether or not this is a correct Base16 representation, only that it conforms to the correct shape. To check whether it is a true Base16 encoded Text value, use isBase16.
