vector_distance is not an optimal name

[Peter]

What is a better name?

distance?

range_distance?

[Markus Ringnér]

distance has the advantage that our functions calculate what is generally meant with distance in physical or mathematical sense. "distance between two points".

distance has the (dis)advantage that std::distance exists. std::distance takes two iterators and calculates the distance between the iterators. Our algorithms take three iterators and calculate the distance between the elements pointed to by iterators in the intervals defined by the three iterators. So our distance is somewhat different from std::distance but it is a well-accepted name and our functions have a different signature than std::distance.

If we do not expect users to be confused about functionality differences between std::distance and yat::distance, we should go for distance.

range_distance is not so good. It seems to be commonly used for distances related to the distance transmitting devices or machine guns can deliver across.

[Peter]

Let's go for distance then.
