A Case Study in Zero-Cost Abstractions in C++ - High Performance Message Dispatch - Luke Valenty - C++Now 2024
---

We often hear about zero-cost abstractions in modern C++. What does that even mean? Why should we want that? How is it possible?

This presentation aims to answer these questions and more through a case study of a message dispatch library. The library uses compile-time programming to create an optimized algorithm for decoding messages and sending them to the appropriate component's message callback.

This is done so we can decouple components and their cross-cutting concerns. Components can register predicated message callbacks without needing to care about other components and their callbacks. The library has all the information it needs at compile-time to implement an efficient dispatching strategy. It is additionally able to provide useful logging information about messages received and messages that don't match any callback.

If you have any interest in high speed message processing, boolean algebra, constant-time lookup algorithms, compile-time programming, or bare metal firmware, please join me on this enlightening case study.
