func main() {
    dir, err := os.MkdirTemp(".", "t-")
    CheckErr(err)

    options := grocksdb.NewDefaultOptions()
    options.SetCreateIfMissing(true)
    options.SetPrefixExtractor(grocksdb.NewNoopPrefixTransform())

    db, err := grocksdb.OpenDb(options, dir)
    CheckErr(err)

    db.Close()
    options.Destroy()
}

func CheckErr(err error) {
    if err != nil {
        panic(err)
    }
