C++ 20 (2a) New Features - Concepts as Compile Time Predicates

This video tutorial focuses on understanding and improving compiler error messages using concepts in C++. It begins with an introduction to the importance of error messages and demonstrates defining a comparison function using the three-way comparison operator. The tutorial then explores error messages that occur when the operator is removed and introduces the use of concepts to enhance these messages. Finally, it shows how to apply concepts to functions and fix code errors, providing a more informative error message experience.

What happens when the spaceship operator is removed from the structure?

What is the first thing to look for when encountering an error message related to concepts?
