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: conversion.go
    path of file: ./repos/kubernetes/staging/src/k8s.io/client-go/scale/scheme/appsv1beta2

	// to kubectl apply). However, these fields are readonly, so any non-nil value should work.
