This infers whether you pass lvalues or rvalues. If passing
further down the chain of such calls is needed, one can use
std.functional : fowrard :
yes...
void variadic(Args...)(auto ref Args args) {
import std.functional : forward;
doStuff(forward!args);
}
void doStuff(Args...)(auto ref Args args) {
/* ... */
}
'forward' aliases ref arguments (i.e. passed lvalues) and moves
value arguments (i.e. passed rvalues).
If a value is not copyable, it may be move-able (check the docs
though, it may not be that either).
void fun(Args...)(auto ref Args args) { /*...*/ }
yes...
import std.algorithm : move;
auto a = NonCopyable(42);
fun(move(a));
// or:
func(NonCopyable(42));
the problem, that I have is, that I would like to use the
templated approach, but I don't have the function, but only a
delegate, so:
template(T, U...)
{
void delegate(ref T neededInput, ref U ignoredInput) dgPtr;
}
Not sure, if this is possible to handle at all...
