Concept definition

template<typename T>
concept vcl::comp::HasQuality =  requires (
    T&&                                 obj,
    typename RemoveRef<T>::QualityType  q,
    typename RemoveRef<T>::QualityType& qR) {
    typename RemoveRef<T>::QualityType;
    { obj.quality() } -> std::convertible_to<decltype(q)>;
 
    
    requires IsConst<T> || requires {

    };
}

Detailed Description

HasQuality concept is satisfied only if a Element class provides the types and member functions specified in this concept. These types and member functions allow to access to a vcl::comp::Quality component of a given element.

Note that this concept does not discriminate between the Horizontal Quality component and the vertical OptionalQuality component, therefore it does not guarantee that a template Element type that satisfies this concept provides Quality component at runtime (it is guaranteed only that the proper member functions are available at compile time).
