Functions

func CRC32CChecksum

func CRC32CChecksum(data []byte) uint32

CRC32CChecksum computes the crc32c checksum of some data

func ParallelCRC32CChecksum

func ParallelCRC32CChecksum(readerAt io.ReaderAt, length int64, opts ParallelChecksumOptions) (uint32, error)

ParallelCRC32CChecksum computes the crc32c checksum for a readerAt using parallelism

func ParallelCRC32CChecksumFile

func ParallelCRC32CChecksumFile(filepath string, opts ParallelChecksumFileOptions) (uint32, error)

ParallelCRC32CChecksumFile is a convenience function that opens a file and computes the crc32c checksum with ParallelCRC32CChecksum
