Detailed Description

C++20 concepts for dependency injection and service container.

This header provides concepts for validating service interfaces, implementations, and factories used in the dependency injection system. These concepts enable compile-time validation with clear 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.
