Workshop - Deduction guides: Impossible is possible, Ruslan Arutyunyan

The presentation will provide the practical example of writing Deductions guides for the class that takes the Callable object as an argument. We are supposed to go through the steps I’ve made to learn how these tasks can be solved. I will demonstrate how to fetch function signature from the object type and then use it as a developer likes, how to leverage the additional information about the required signature of a function, and how to make more convenient user interface based on above. The presentation is going to tell the quite funny story of how impossible becomes possible just in two days. The attendees are expected to know what is Class Template Argument Deduction (CTAD) and basics about how to write the Deduction Guides.
