Struct template not_equal_to

boost::proto::not_equal_to — A metafunction for generating not-equal-to expression types, a grammar element for matching not-equal-to expressions, and a PrimitiveTransform that dispatches to the proto::pass_through<> transform.


// In header: <boost/proto/traits.hpp>

template<typename T, typename U> 
struct not_equal_to :  proto::transform< not_equal_to<T, U> > {
  // types
  typedef proto::expr< proto::tag::not_equal_to, proto::list2< T, U > >       type;         
  typedef proto::basic_expr< proto::tag::not_equal_to, proto::list2< T, U > > proto_grammar;

  // member classes/structs/unions
  template<typename Expr, typename State, typename Data> 
  struct impl :
     proto::pass_through<mot_equal_to>::template impl<Expr, State, Data>
