Exploring the Standard Concepts Library
Explore the C++20 standard concepts library to understand how to apply fundamental concepts and constraints to template arguments. Learn about core language, comparison, object, and callable concepts, as well as new iterator and ranges concepts introduced in C++20 to write safer and more readable template code.
The standard concepts library
The standard library provides a set of fundamental concepts that can be used to define requirements on the template arguments of function templates, class templates, variable templates, and alias templates, as we have seen throughout this section. The standard concepts in C++20 are spread across several headers and namespaces. We’ll present some of them in this lesson although not all of them (see the Further Readings section at the end of this course).
The main set of ...
