Concept definition

template<typename METRIC, typename T>
concept metric = std::integral<T> && requires (T t, glm::tvec2<T> vec) {

is_adjacent(vec, vec) should return whether two squares are adjacent

        { METRIC::is_adjacent(vec, vec) } -> std::convertible_to<bool>;

is_adjacent(direction) should return whether a square in the direction of another square is adjacent

        { METRIC::is_adjacent(direction{}) } -> std::convertible_to<bool>;

distance(vec, vec) should return a tile distance between two tile positions within this metric. Note that this is different than the concept of distances in a world (where tiles have sizes). The distance here can be thought of as the minimum number of 'hops' between adjacent squares to move from one position to another.

        { METRIC::distance(vec, vec) } -> std::convertible_to<T>;
    }

Detailed Description

Any type that meets the criteria of a metric - specifying the adjacency/distances between squares.
