Detailed Description

C++20 concepts for logger interfaces.

This header provides concepts for validating logger types used in logging operations. These concepts replace abstract class-based constraints with compile-time validation and clearer error messages.

Requirements:

• C++20 compiler with concepts support
• GCC 10+, Clang 10+, MSVC 2022+

Thread Safety:

• Concepts are evaluated at compile-time only.
• No runtime thread-safety considerations apply.
