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?

Definitely let go. Rust has some OOP features, but it's mostly just the OOP idea of interfaces, which Rust models with traits. You can also do dynamic dispatch, which is another OOP feature, but you should almost never use this in Rust unless you absolutely have to. Then there's encapsulation which is hugely important in Rust too, but yea outside of that kind of thing, I don't think OOP patterns are too useful. Honestly, if you ask me, many of these "OOP patterns" are really just solving problems that OOP causes in the first place.

Feel free to ask any other questions.
