Summary of the talk:
C++20 introduced a nice formatting library with std::format(). This session will explain what the formatting library provides, how to use all of its functionality, and most importantly, how you can customize it so that you can use formatting strings that include your very own custom types and custom formatting parameters, and of course, how to handle errors.
