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: conn.go
    path of file: ./repos/codis/vendor/github.com/samuel/go-zookeeper/zk
    
    the code of the file until where you have to start completion: // Package zk is a native Go client library for the ZooKeeper orchestration service.
package zk

/*

func (c *Conn) Set(path string, data []byte, version int32) (*Stat, error) {
	if path == "" {
		return nil, ErrInvalidPath
	}
	res := &setDataResponse{}
	_, err := c.request(opSetData, &SetDataRequest{path, data, version}, res, nil)
	return &res.Stat, err
}
