Data.Memory.Endian

Description

 

Synopsis

Documentation

data Endianness Source

represent the CPU endianness

Big endian system stores bytes with the MSB as the first byte. Little endian system stores bytes with the LSB as the first byte.

middle endian is purposely avoided.

Constructors

fromBE :: ByteSwap a => BE a -> a Source

Convert from a big endian value to the cpu endianness

toBE :: ByteSwap a => a -> BE a Source

Convert a value in cpu endianess to big endian

fromLE :: ByteSwap a => LE a -> a Source

class Storable a => ByteSwap a Source

Class of types that can be byte-swapped.

e.g. Word16, Word32, Word64
