You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: path.go
    path of file: ./repos/devspace/vendor/sigs.k8s.io/kustomize/kyaml/yaml/internal/k8sgen/pkg/util/validation/field
    
    the code of the file until where you have to start completion: // Code generated by k8scopy from k8s.io/apimachinery@v0.19.8; DO NOT EDIT.
// File content copied from k8s.io/apimachinery@v0.19.8/pkg/util/va
    
func (p *Path) String() string {
	// make a slice to iterate
	elems := []*Path{}
	for ; p != nil; p = p.parent {
		elems = append(elems, p)
	}

	// iterate, but it has to be backwards
	buf := bytes.NewBuffer(nil)
	for i := range elems {
		p := elems[len(elems)-1-i]
		if p.parent != nil && len(p.name) > 0 {
			// This is either the root or it is a subscript.
			buf.WriteString(".")
		}
		if len(p.name) > 0 {
			buf.WriteString(p.name)
		} else {
			fmt.Fprintf(buf, "[%s]", p.index)
		}
	}
	return buf.String()
}
