// @note This is a smart pointer class that is compatible with std::shared_ptr, but it is more lightweight and do not
//       use atomic operation for reference counting. It is designed for single thread usage.
// @note We support all APIs of std::shared_ptr in C++14, and partly APIs of std::shared_ptr in C++17/20/26.
