An Adventure in Modern Library Design - Robert Leahy - C++Now 2024
---

Library design used to seem easy: Model the problem domain with classes which sometimes inherit from one another, throw in a few free functions, and you’re done. Modern library design is unrecognizable from that frame of reference: Customization point objects, expression equivalence, perfect forwarding, a seemingly-endless list of edge cases and sharp edges understood only by experts.

This journey from simple to complicated didn’t occur without reason. Putting complexity into libraries transfers that complexity into a single place where it can be dealt with once. Improving genericity by considering and handling edge cases and seemingly-obscure use cases furthers the concentration of complexity by increasing the reach and leverage of C++ libraries.

This talk will explore modern C++ library design principles using the real-world example of a library which interfaces with a time series database. CPOs and generic algorithms form the foundation of this C++ library. Sophisticated uses of std::variant, CTAD, and immovable types will be introduced. Attendees will gain actionable insights into designing modern C++ libraries to address complex software engineering challenges.
