I read the source code and I do not understand
template<class ...Args>
  bool write(Args&&... recordArgs) {

in this function

template<class ...Args>
  bool write(Args&&... recordArgs) {
auto const currentWrite = writeIndex_.load(std::memory_order_relaxed);
auto nextRecord = currentWrite + 1;
if (nextRecord == size_) {
   nextRecord = 0;
}
if (nextRecord != readIndex_.load(std::memory_order_acquire)) {
   new (&records_[currentWrite]) T(std::forward<Args>(recordArgs)...);
   writeIndex_.store(nextRecord, std::memory_order_release);
   return true;
}

// queue is full
return false;
  }

TIA
