Struct template function

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

Synopsis

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

template<typename... A> 
struct function :  proto::transform< function<A...> > {
  // types
  typedef proto::expr< proto::tag::function, proto::listN< A... > > type;           
  typedef type                                                      proto_base_expr;

  // member classes/structs/unions
  template<typename Expr, typename State, typename Data> 
  struct impl :
     proto::pass_through<function>::template impl<Expr, State, Data>
  {
  };
};
