Experience

Assertive Multithreading Library

https://github.com/msterkowiec/AMTL/
A library aimed at enhancing and ensuring code robustness. The assertive multithreading library is intended to have no impact on actual release builds. Its primary purpose is to provide types for special builds—debugs or special releases—that can detect various errors in the code during runtime.

The idea to build this library sprang into my mind in the middle of April 2021, during bug fixing of a piece of software that solves chess problems. Currently, the library has the potential to make C++ code as robust as Rust programs are said to be without losing the freedom that C++ offers.
