parseHex : Char -> Maybe (Fin 16)hexDigit : Fin 16 -> CharleftPad : Char -> Nat -> String -> StringfromHexLittleEndian : String -> Maybe IntegerConvert little-endian hex-string to Integer.
Fails if the string doesn't represent a hexadecimal number.
As for the latin letters in the hex-string, both lower- and upper- case letters represent valid hex characters.
Examples of valid hex-strings:
FFF ✔
fEA ✔
hello ✗
1F62aA7 ✔
fromHexBigEndian : String -> Maybe IntegerJust like `fromHexLittleEndian` but for big-endian hex-strings.
