Type Requirements - Require the Existence of a Nested Type
Explore how to use type requirements in C++ Concepts to enforce the presence of nested types within template parameters. Understand how this improves type safety by allowing the compiler to validate template constraints and provide clearer error messages for invalid types.

Introduction
With type requirements, we can express that a certain type is only valid in a specific context. Type requirements can be used to verify if:
