I’m writing a web app at work and I have one Arc and no Rc or RefCell.

Got zero because I cheated with Box::leak

Haha!

Have you ever written a web app in Rust? Most of the code is in a form of handlers that receive data, process the data and give some data back. There is rarely need to think about lifetimes or borrowing in these scenarios.

Show me what you find to be hard, because I don't believe you.

None of what you've described is hard. It's quite approachable, and an IDE with an LLM practically autocompletes everything for you anyway.

If you can write Java or Go, you can absolutely write Rust.

I would have thought async would be the biggest problem.

If you're in a web framework, all the handlers are async already. You have literally no work to do.
