func Diff

func Diff(old, new []byte, granularity int) (patch []byte)

Diff computes the difference between old and new. A granularity of 1 or more combines changes with no greater than that many bytes between them.

func Forward

func Forward(old, patch []byte) (new []byte, err error)

Forward retrieves the second argument to Diff given the first argument and its output.

func Reverse

func Reverse(new, patch []byte) (old []byte, err error)

Reverse retrieves the first argument to Diff given the second argument and its output.
