Post Body

I'm coming over from C background. The lesson for today was error handling. I set myself a task of defining three custom errors and handling them together with "naturally arising errors"

https://github.com/fireice-uk/rus_errors/blob/main/src/main.rs

I have defined three error types ErrorNumberIsOne ErrorNumberIsTwo ErrorNumberIsOther - any way to cut the boilerplate code there? I tried to make them somehow "inherit" off a shared base but couldn't get it to work
Any way to get the error handling on line 90 to work?
Any way to reduce boilerplate on 102 - 112?
