func CRC32CChecksum(data []byte) uint32

CRC32CChecksum computes the crc32c checksum of some data

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

ParallelCRC32CChecksum computes the crc32c checksum for a readerAt using parallelism

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

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

type ParallelChecksumFileOptions struct {
	Concurrency int
	PartSize    int64
	Mmap        bool
}

ParallelChecksumFileOptions are the options for running a parallelized checksum on a file
