asSigned :: forall a. a -> Signed a

Coerce a value into a positive signed value

mkHexString :: String -> Maybe HexString

unHex :: HexString -> String

hexLength :: HexString -> Int

Compute the length of the hex string, which is twice the number of bytes it represents

dropHex :: Int -> HexString -> HexString

takeHex :: Int -> HexString -> HexString

nullWord :: HexString

getPadLength :: Int -> Int

Utils Computes the number of 0s needed to pad a bytestring of the input length

padLeftSigned :: Signed HexString -> HexString

Pad a Signed HexString on the left until it has length == 0 mod 64.

padLeft :: HexString -> HexString

Pad a HexString on the left with '0's until it has length == 0 mod 64.

padRightSigned :: Signed HexString -> HexString

Pad a Signed HexString on the right until it has length 0 mod 64.

padRight :: HexString -> HexString

Pad a HexString on the right with 0's until it has length 0 mod 64.

toUtf8 :: HexString -> String

Takes a hex string and produces the corresponding UTF8-decoded string. This breaks at the first null octet, following the web3 function toUft8.

fromUtf8 :: String -> HexString

Get the 'HexString' corresponding to the UTF8 encoding.

toAscii :: HexString -> String

Takes a hex string and produces the corresponding ASCII decoded string.

fromAscii :: String -> HexString

Get the 'HexString' corresponding to the ASCII encoding.

toSignedHexString :: BigNumber -> Signed HexString

toHexString :: BigNumber -> HexString

toBigNumber :: HexString -> BigNumber

toBigNumberFromSignedHexString :: HexString -> BigNumber

toByteString :: HexString -> ByteString

fromByteString :: ByteString -> HexString
