Best practice to avoid "dangling transaction"

[fluxxu]

https://docs.rs/diesel-async/0.2.0/diesel_async/trait.AsyncConnection.html#method.transaction

WARNING: Cancling the returned future does currently not close an already open transaction. You may end up with a connection containing a dangling transaction.

Is there any suggestion to avoid this problem, as I understand it, even if I don't actively cancel a future, maybe the framework I'm using, or the library function might do it implicitly?

Thank you.

We do explicitly not provide suggestions how to avoid this problem as this is currently inherent on how rust async ecosystem is designed. That's the reason why this is documented this way.
