func GetBufSize() uint64

func SetBufSize(bs int)

type Checksum struct {
	Filename string
	Path     string
	CRC32    uint32
}

Checksum represents a line in a SFV file, containing the filename, full path to the file and the CRC32 checksum

func (c *Checksum) IsExist() bool

IsExist returns a boolean indicating if the file associated with the checksum exists

func (c *Checksum) Verify(polynomial uint32) (bool, uint32, error)

Verify calculates the CRC32 of the associated file and returns true if the checksum is correct along with the calculated checksum

type SFV struct {
	Checksums []Checksum
	Path      string
}

SFV contains all the checksums read from a SFV file.

func Find(path string) (*SFV, error)

Find tries to find a SFV file in the given path. If multiple SFV files exist in path, the first one will be returned.

func Read(filepath string) (*SFV, error)

Read reads a SFV file from filepath and creates a new SFV containing checksums parsed from the SFV file.

func (s *SFV) IsExist() bool

IsExist returns a boolean if all the files in SFV exists

func (s *SFV) Verify(polynomial uint32) (bool, error)

Verify verifies all checksums contained in SFV and returns true if all checksums are correct.
