Dominoes posted:My ROT: If you use a `Fn` trait and you get compile errors, prepend `dyn`, If that doesn't work, also wrap it in a box. If you give up, use a `fn` pointer instead. I hate that I’ve been using Rust for a few months now and I have no idea what this means.

I’m working with a couple giant RESTful actix apps. I guess if I looked under the hood more I’d see those higher order functions in action.

Advice on stack overflow is often invalid if it’s more than a couple years old. Library documentation isn’t great, and sometimes there’s just no one (publicly) using the function you’re trying to figure out.

The Result and Option and match and enum are so good. Everyone talks about the speed and memory management, but for me it’s all about those algebraic data types. I had to build an SDK in Go a couple weeks ago, and on one hand I like that it doesn’t have null values, but where was my Option?

What’s the best practice for storing simple enums in a database? I’ve been manually implementing Display and FromStr to make it easy to convert to and from an SQL text column, but is there a better way?

gonadic io posted:How simple? If there's no (and can never be) any fields in any of the variants, then that's a job for the ol' integer. Exactly that simple. I haven’t used enum discriminants. How do I convert from an integer back to the enum? Google is telling me I need to write a try_from function. Is that correct?
