Types

type RDiff

type RDiff interface {
	ComputeHashes(file *os.File) ([]chunk, error)
	ComputeDelta(original, updated *os.File) ([]byte, error)
}

type RollingHash

type RollingHash struct {
	// contains filtered or unexported fields
}

func NewRollingHash

func NewRollingHash(chunkSize int) *RollingHash

NewRollingHash returns a new RollingHash struct

func (*RollingHash) ComputeDelta

func (r *RollingHash) ComputeDelta(original, updated *os.File) ([]byte, error)

ComputeDelta generates a description of the differences between the original and updated versions of a file

func (*RollingHash) ComputeHashes

func (r *RollingHash) ComputeHashes(file *os.File) ([]chunk, error)

ComputeHashes reads a file in chunks and computes the hash of each chunk using the SHA1 hash function
