Guarantees about re-rendering and setState batching inside an event handler

Hi,
I have React 17 and I am using hooks. I believe answer is hinted by "Multiple updates inside event handlers get batched into a single update." ... https://reactjs.org/docs/implementation-notes.html#what-we-left-out , but I am not 100% sure I understand it correctly.

Does React guarantee that while my event handler is being processed no re-render happens? That is first re-render happens after my event handler exits.

  const onClick = () => {
    setState1(1);
    // do some stuff
    setState1(2);
    // do some stuff
    setState4(4);

    // no-rerender will ever be called by React until this point (that is until function returns) ???
    // re-render is only scheduled to happen ASAP
  } 

Thanks for answering :)

先閱讀連結的 React 實作說明，並檢查問題中所描述的 React 17 事件處理器批次處理行為。確定文件是否應說明有關重新渲染時機和 setState 批次處理的保證，然後在確認預期措辭和範圍後更新相關文件。
