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: client_info.go
    path of file: ./repos/sliver/vendor/gopkg.in/jcmturner/gokrb5.v7/pac
    
    the code of the file until where you have to start completion: package pac

import (
	"bytes"

	"gopkg.in/jcmturner/rpc.v1/mstypes"
)

// ClientInfo implements https://msdn.microsoft.com/en-us/library/cc237951.aspx
type ClientInfo struct {
	ClientID   mstypes.FileTime // A FILETIME structure in little-endian format that contains the K
    
func (k *ClientInfo) Unmarshal(b []byte) (err error) {
	//The PAC_CLIENT_INFO structure is a simple structure that is not NDR-encoded.
	r := mstypes.NewReader(bytes.NewReader(b))

	k.ClientID, err = r.FileTime()
	if err != nil {
		return
	}
	k.NameLength, err = r.Uint16()
	if err != nil {
		return
	}
	k.Name, err = r.UTF16String(int(k.NameLength))
	return
}
