C does meet the CopyInsertible requirements:
https://godbolt.org/z/8j7KcbhdM
#include <memory>
class C {
const int m_x;
public:
C(int x) : m_x (x) {}
};
int main()
{
// C is CopyInsertable:
{
alignas(C) char mem[sizeof(C)];
auto v = C(42);
C* c = ::new((void*)mem) C(v);
c->~C();
}
{
alignas(C) char mem[sizeof(C)];
auto v = C(42);
C* c = std::construct_at ((C*)mem, v);
c->~C();
}
}
