Concept definition

template<typename T>
concept ExcluderType =
    requires(T& excluder, const stk::mesh::BulkData& bulk_data, const stk::mesh::Selector& target_selector,
             const stk::mesh::Selector& source_selector, const NeighborSearchCandidate<size_t>& candidate) {
      { excluder.setup(bulk_data, target_selector, source_selector) } -> std::same_as<void>;
      { std::as_const(excluder)(candidate) } -> std::convertible_to<bool>;
    }

Detailed Description

Excluders are stored in the builder and prepared during neighbor-list construction. setup(...) gives an excluder a chance to cache selector- and mesh-dependent state before backend callbacks apply it to candidate pairs. operator() must be callable on at least NeighborSearchCandidate<size_t> (checked here as a representative non-periodic candidate type; excluders that also handle periodic candidates do so via their own template overloads).
