concept kcenon::common::concepts::AssociativeContainer =  Container<T> && requires(T t) {
    typename T::key_type;
    { t.find(std::declval<typename T::key_type>()) } -> std::same_as<typename T::iterator>;

}

Detailed Description

A container that provides key-based access.

Associative containers support find, count, and key-based operations.

template<AssociativeContainer C>
bool contains_key(const C& container, typename C::key_type key) {
    return container.find(key) != container.end();
}
