Method allocate

test-app/runtime/src/main/cpp/robin_hood.h:417–425

allocates, but does NOT initialize. Use in-place new constructor, e.g. T* obj = pool.allocate(); ::new (static_cast (obj)) T();

    //   T* obj = pool.allocate();
    //   ::new (static_cast<void*>(obj)) T();
    T* allocate() {
        T* tmp = mHead;
        if (!tmp) {
            tmp = performAllocation();
        }

        mHead = *reinterpret_cast_no_cast_align_warning<T**>(tmp);
        return tmp;
    }

    // does not actually deallocate but puts it in store.
    // make sure you have already called the destructor! e.g. with
