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: kb_version.go
    path of file: ./repos/grype/grype/version
    
    the code of the file until where you have to start completion: package version

import (
	"fmt"
	"reflect"
)

type kbVersion struct {
	version string
}

func newKBVersion(raw string) kbVersion {
	// XXX Is this even useful/necessary?
	retu
    
func (v *kbVersion) Compare(other *Version) (int, error) {
	if other.Format != KBFormat {
		return -1, fmt.Errorf("unable to compare kb to given format: %s", other.Format)
	}

	if other.rich.kbVer == nil {
		return -1, fmt.Errorf("given empty kbVersion object")
	}

	return other.rich.kbVer.compare(*v), nil
}
