transaction question

[MateSoftware2023]

Whether the transaction is automatically rolled back if it fails to commit. When I try to display a rollback, it prompts me that I have no ownership.
if let Err(err) = tx.commit().await {
if let Err(rollback_err) = tx.rollback().await {
...
} else {
...
}
};

what are you trying to do?
After completing the transaction via tx.commit(), rolling it back does not make any sense any longer.
