Understanding The constexpr 2Step Jason Turner C++ on Sea 2024


C++20 enabled both std::vector and std::string for constexpr usage. However, this simple case does not compile:

constexpr std::vectorintdata{1,2,3,4,5};

If we cannot create constexpr strings and vectors, then what good are they for constexpr use?

This talk will cover the "constexpr twostep." A method of getting data of unknown size generated at compile time into the runtime world while minimizing binary sizes in the process.
