Concept definition

template<typename T>
concept kcenon::common::concepts::LevelAwareLogger =  BasicLogger<T> &&
    requires(T t, const T ct, interfaces::log_level level) {
        { ct.is_enabled(level) } -> std::convertible_to<bool>;
        { t.set_level(level) };
        { ct.get_level() } -> std::convertible_to<interfaces::log_level>;
    }

Detailed Description

A type that supports log level filtering.

Types satisfying this concept can check if a log level is enabled and can set/get the minimum log level. This enables efficient logging by avoiding unnecessary message formatting.

Example usage:

template<LevelAwareLogger L>
void log_debug(L& logger, const std::string& message) {
    if (logger.is_enabled(interfaces::log_level::debug)) {
        logger.log(interfaces::log_level::debug, message);
    }
}
