How to Build C++ Interfaces That Are Hard to Use Incorrectly - Lecture

Explore techniques for building robust C++ interfaces that minimize accidental misuse in this conference talk from C++ on Sea 2023. Learn how to leverage the C++ type system to push precondition violation detection from run-time to compile-time, reducing opportunities for bugs in user code. Discover design strategies for distinguishing precondition categories, preventing interface misuse through type-based techniques, and examining the trade-offs of this approach. Gain insights into creating portable code and exposing complex functionalities through simple, richly-typed interfaces as presented by Andreas Weis, an experienced C++ developer and library writer.
