type Base85 = UInt

Represents a single base85 digit between 0 and 84

#Base256 Source

type Base256 = UInt

Represents a single base256 digit between 0x00 and 0xFF - a Byte

Instances

#getZ85Char Source

getZ85Char :: Z85Char -> Char

#Z85Chunk Source

type Z85Chunk = Vec D5 Z85Char

Represents a 32-bit word encoded as 5 z85 characters

#z85Chars Source

z85Chars :: String

Sorted by their value in the z85 encoding

#inZ85Charset Source

inZ85Charset :: String -> Boolean

#allZ85Chars Source

allZ85Chars :: Array Z85Char

#lookupZ85Char Source

lookupZ85Char :: Base85 -> Z85Char

#charCodeToBase85 Source

charCodeToBase85 :: Array Base85

Reverse-sorted by the lookup index obtained by getting the UTF-16 char code value, minus 32 - the equivalent of "n".charCodeAt(0) - 32 in JavaScript, where n is some x85 character.

#lookupBase85 Source

lookupBase85 :: Z85Char -> Base85

#encodeWord Source

encodeWord :: UInt -> Z85Chunk

Encodes the value by extracting it out of a little-endian packed word, and packing it into five x85 chars

#decodeWord Source

decodeWord :: Z85Chunk -> UInt
