A Totally Constexpr Standard Library - Enhancing C++ Compile-Time Capabilities

Explore the future of C++ programming in this conference talk from Meeting C++ 2022. Delve into the concept of a fully constexpr standard library, made possible by C++20's support for dynamic memory allocation during constant evaluation. Learn about the C'est library project, which extends constexpr functionality to various class templates inspired by the C++ standard library. Discover the updated C'est architecture designed to simplify integration into projects targeting constexpr support. Examine real-world applications, including a compile-time compiler and a Metamath proof database verifier. Gain insights into the advantages of compile-time and run-time programming parity, while considering the impact on compilation times. Investigate CTBench, a set of tools for comprehensive compile-time benchmarking based on Clang's time-trace feature.
