Data.Digest.CRC32

Description

CRC32 wrapper

Synopsis

- class CRC32 a where
  - crc32 :: a -> Word32
  - crc32Update :: Word32 -> a -> Word32

# Documentation

class CRC32 a where

The class of values for which CRC32 may be computed

Minimal complete definition

crc32Update

Methods

crc32 :: a -> Word32

Compute CRC32 checksum

crc32Update :: Word32 -> a -> Word32

Given the CRC32 checksum of a string, compute CRC32 of its concatenation with another string (t.i., incrementally update the CRC32 hash value)
