Detailed Description

C++20 concepts for unified socket abstraction.

This header provides concepts for compile-time validation of socket types, enabling generic algorithms to work with different socket implementations (tcp_socket, secure_tcp_socket, udp_socket, websocket_socket).

Concept hierarchy:

• Socket: Base concept for all socket types (close, is_closed)
• StreamSocket: Connected sockets with async send/receive (tcp, secure_tcp)
• DatagramSocket: Connectionless sockets with send_to (udp)
• MessageSocket: Message-oriented sockets (websocket)

Requirements:

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