Collaboration diagram for kcenon::network::unified::connection_callbacks:

Public Attributes
std::function< void()>	on_connected
	Called when connection is established.

std::function< void(std::span< const std::byte >)>	on_data
	Called when data is received (raw bytes)

std::function< void()>	on_disconnected
	Called when connection is closed.

std::function< void(std::error_code)>	on_error
	Called when an error occurs.

Detailed Description

Callback functions for connection events.

Groups all callback functions that can be registered for connection lifecycle events. All callbacks are optional (can be empty).

Thread Safety

Callbacks may be invoked from I/O threads. Implementations must ensure their callbacks are thread-safe if they access shared state.

Examples

connection_callbacks cbs;
cbs.on_connected = []() {
    std::cout << "Connected!" << std::endl;
};
cbs.on_data = [](std::span<const std::byte> data) {
    // Process received data
};
cbs.on_disconnected = []() {
    std::cout << "Disconnected!" << std::endl;
};
cbs.on_error = [](std::error_code ec) {
    std::cerr << "Error: " << ec.message() << std::endl;
};
