如何像uint64_t一样向rocksdb中插入整数值？

#include <rocksdb/db.h>

int main() {
    rocksdb::DB* db;
    rocksdb::Options options;
    options.create_if_missing = true;

    rocksdb::Status status = rocksdb::DB::Open(options, "/path/to/db", &db);
    if (!status.ok()) {
        // 处理数据库打开失败的情况
        return -1;
    }

    uint64_t key = 12345;
    uint64_t value = 98765;

    std::string keyStr(reinterpret_cast<const char*>(&key), sizeof(key));
    std::string valueStr(reinterpret_cast<const char*>(&value), sizeof(value));

    status = db->Put(rocksdb::WriteOptions(), keyStr, valueStr);
    if (!status.ok()) {
        // 处理插入数据失败的情况
        return -1;
    }

    delete db;
    return 0;
}
