This module provides an implementation of RFC 6902.
There are other go libraries that provide similar functionality. The difference between the rest and this is that instead of using the patch to create a JSON []byte array it applies the patch to a go type.
The library exposes two APIs Apply and Diff(to be done).
func Apply(data []byte, x interface{}) error
func Diff(a, b interface{}) ([]byte, error)
It should be noted that Apply makes a recursive copy of the value passed to the function. It applies the changes only if all of the operations in the patch succeeded.
The repository also provides a module deep which exposes an API Copy.
func Copy(x, y interface{}) error
It makes a recursive copy of x into y.
