Struct template equal_to

boost::proto::equal_to — A metafunction for generating equal-to expression types, a grammar element for matching equal-to expressions, and a PrimitiveTransform that dispatches to the proto::pass_through<> transform.

Synopsis

template<typename T, typename U> 
struct equal_to :  proto::transform< equal_to<T, U> > {
  // types
  typedef proto::expr< proto::tag::equal_to, proto::list2< T, U > > type;           
  typedef type                                                      proto_base_expr;
  template<typename Expr, typename State, typename Data> 
  struct impl :
     proto::pass_through<equal_to>::template impl<Expr, State, Data>
  {
  };
};
