sqlx::Transaction and Arc<Mutex> (lemm.ee)

submitted 2 weeks ago by [email protected] to c/[email protected]

17 comments fedilink hide all child comments

In order to share the running transaction into a DAO style data management class, I have wrapped the transaction in an Arc and pass it into the DAO.

The issue is, once the transaction is in there I cannot call commit() on it because it cannot be moved out of the Arc anymore, as the commit requires a mut self.

Any ideas on how to work around this?

Not talking threads here, more Tokio tasks.

You appear to be generally confused.

If you're using the multi-threaded work-stealing tokio runtime (the default), you are "talking threads". And if you aren't, Arc and Mutex would be useless, irregardless of whether you're doing it right or wrong.
