Program Listing for File forward.hpp

↰ Return to documentation for file (include/ripple/utility/forward.hpp)

/*
 * std::forward and std::move require utility, which along with the need to do
 * name lookup, overload resolution, and template instantiation, and the compile
 * time effects are significant.
 *
 * When modules are supported by nvcc, we can remove these macros and use
 * std::forward and std::move.
