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: asset.go
    path of file: ./repos/OpenDiablo2/d2common/d2loader/mpq
    
    the code of the file until where you have to start completion: package mpq

import (
	"fmt"
	"path/fi
    
func (a *Asset) Close() (err error) {
	// Calling a.stream.Close() will set the stream to nil, we dont want to do that.
	// Because this asset gets cached, it may get retrieved again and used, in which
	// case we will want the stream ready. So, instead of closing, we just seek back to the start.
	// The garbage collector should get around to it if it ever gets ejected from the cache.
	_, err = a.Seek(0, 0)
	return err
}
