Z.Data.Array.Unaligned

Description

This module implements unaligned element access with ghc primitives (> 8.6), which can be used as a simple binary encoding / decoding method.

Synopsis

Documentation

class Unaligned a where Source #

Primitive types which can be unaligned accessed

It can also be used as a lightweight method to peek/poke value from/to C structs when you pass MutableByteArray# to FFI as struct pointer, e.g.

 -- | note the .hsc syntax
 peekSocketAddrMBA :: HasCallStack => MBA## SocketAddr -> IO SocketAddr
 peekSocketAddrMBA p = do
     family <- peekMBA p (#offset struct sockaddr, sa_family)
     case family :: CSaFamily of
         (#const AF_INET) -> do
             addr <- peekMBA p (#offset struct sockaddr_in, sin_addr)
             port <- peekMBA p (#offset struct sockaddr_in, sin_port)
             return (SocketAddrInet (PortNumber port) addr)
         ....

Methods

unalignedSize :: UnalignedSize a Source #

byte size

indexWord8ArrayAs# :: ByteArray# -> Int# -> a Source #

index element off byte array with offset in bytes(maybe unaligned)

readWord8ArrayAs# :: MutableByteArray# s -> Int# -> State# s -> (# State# s, a #) Source #

read element from byte array with offset in bytes(maybe unaligned)

writeWord8ArrayAs# :: MutableByteArray# s -> Int# -> a -> State# s -> State# s Source #

write element to byte array with offset in bytes(maybe unaligned)

peekMBA :: MutableByteArray# RealWorld -> Int -> IO a Source #

IO version of writeWord8ArrayAs# but more convenient to write manually.

pokeMBA :: MutableByteArray# RealWorld -> Int -> a -> IO () Source #

IO version of readWord8ArrayAs# but more convenient to write manually.

indexBA :: ByteArray# -> Int -> a Source #

index element off byte array with offset in bytes(maybe unaligned)
