Concept definition

template<typename It, typename Arc>
concept GraphArcIterator =  BasicGraphIterator<It> && requires(const It cit)
{
  { cit.get_curr() } -> std::convertible_to<Arc*>;
}

Detailed Description

Concept for graph arc iterators.

An arc iterator must satisfy BasicGraphIterator and return a pointer to the specified Arc type from get_curr().

This concept is useful when you need to ensure the iterator yields arcs of a specific type.

Template Parameters

It	The iterator type to check
Arc	The expected arc type (not pointer)
