xieite::group<>

Defined in header <xieite/meta/group.hpp>

"Groups" some types into singular "things". Can be used on C-style arrays, function pointers, and function references.
Differs from std::type_identity_t<> in that this does not prevent template parameter deduction (see example).


Declaration

 
template<typename T>
using group = T;


Example

 
template<typename Ret>
void foo(xieite::group<Ret(&)()> fn) {
	fn();
}

int bar() {
	std::puts("bar");
	return 0;
}

float baz() {
	std::puts("baz");
	return 0.0f;
}

int main() {
	foo(bar);
	foo(baz);
}
Output: 
bar
baz
