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

submitted 5 days ago by Cpo@lemm.ee to c/rust@programming.dev

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?

If I understand correctly, each data-access structure represents single workflow, and you may have Transaction in that structure without the need for Arc<Mutex<…>> inside, but maybe you will need to wrap the structure itself with that.
