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

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?

Make sure there’s only one strong reference and call Arc::into_inner to move it out of the Arc. Same can be done with Mutex::into_inner to move the transaction out of the mutex

Thanks! Will try that!
