Data.Memory.Encoding.Base16
Description
Low-level Base16 encoding and decoding.
If you just want to encode or decode some bytes, you probably want to use the Data.ByteArray.Encoding module.
Synopsis
- showHexadecimal :: (forall a. (Ptr Word8 -> IO a) -> IO a) -> Int -> String
- toHexadecimal :: Ptr Word8 -> Ptr Word8 -> Int -> IO ()
- fromHexadecimal :: Ptr Word8 -> Ptr Word8 -> Int -> IO (Maybe Int)
Documentation
Arguments
:: (forall a. (Ptr Word8 -> IO a) -> IO a) | a |
-> Int | length in bytes |
-> String |
Transform a raw memory to an hexadecimal String
user beware, no checks are made
Arguments
:: Ptr Word8 | destination memory |
-> Ptr Word8 | source memory |
-> Int | number of bytes |
-> IO () |
Transform a number of bytes pointed by.src in the hexadecimal binary representation in
dst
destination memory need to be of correct size, otherwise it will lead to really bad things.
fromHexadecimal :: Ptr Word8 -> Ptr Word8 -> Int -> IO (Maybe Int) Source #
convert a base16 src in
dst.
