close method

void close()

Undeclares the publisher and releases native resources.

Safe to call multiple times -- subsequent calls are no-ops.

Implementation

void close() {
  if (_closed) return;
  _closed = true;
  bindings.zd_publisher_drop(_ptr.cast());
  _matchingPort?.close();
  _matchingController?.close();
  calloc.free(_ptr);
}
