Non Thread Safe Smart Pointer
this repository is for the implementations of non-thread-safe smart pointers.

features:

1. because of non-thread-safe, it will work fast.
2. these are formatted like STL smart pointers, thus these will replace STL ones easily.
3. running with single header file.
4. can be compiled on c++17 or later.

but these don't have functions as many as STL yet. basic functions only.
for usage, please see tests.cpp.
