boost::proto::functional::as_env::result
// In header: <boost/proto/transform/env.hpp>
template<typename Sig>
struct result {
// types
typedef see-below
type;
};
Encodes the return type of proto::functional::as_env::operator()
.
The presence of this member template makes proto::functional::as_env
a valid TR1-style function object type usable with boost::result_of<>
.
