Detailed Description

Unified header for all C++20 concepts in network_system.

This header provides a single include point for all concepts defined in the network_system library. Including this header gives access to all concept definitions for compile-time type validation.

Available concept categories:

• Buffer concepts: ByteBuffer, MutableByteBuffer
• Callback concepts: DataReceiveHandler, ErrorHandler, SessionHandler
• Component concepts: NetworkClient, NetworkServer, NetworkSession
• Pipeline concepts: DataTransformer, ReversibleDataTransformer

When KCENON_WITH_COMMON_SYSTEM is defined, this header also provides access to common_system concepts:

• Result/Optional: Resultable, Unwrappable, Mappable
• Callable: Invocable, VoidCallable, Predicate

Requirements:

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

Example usage:

#include <kcenon/network/concepts/concepts.h>
 
using namespace kcenon::network::concepts;
 
template<DataReceiveHandler Handler>
void set_handler(Handler&& handler) {
    // Handler will be called with const std::vector<uint8_t>&
}
 
template<NetworkClient Client>
void send_data(Client& client, std::vector<uint8_t> data) {
    if (client.is_connected()) {
        client.send_packet(std::move(data));
    }
}

Benefits of using concepts:

• Clearer error messages: Template errors are displayed as concept violations instead of verbose SFINAE failures
• Self-documenting code: Concepts express type requirements explicitly
• Better IDE support: More accurate auto-completion and type hints
