Error handling in Rust

Rust should seriously stop using macros for everything.

What's wrong with macros?

Especially attribute style macros which apply to variants of an enum allow a lot of code expansion which reduces boilerplate a lot.

Increase of compile times, on a already blazing fast compiler.

Debugging, especially when it lacks the tooling of a Lisp or Scheme REPL/IDE.

I agree with this. It appears that in this case, macros are a band-aid over missing features in the type system.

I feel like structural typing or anonymous sum types would solve this problem without macros.

I mean given A = X | Y and B = X | Y | Z, surely the compiler can tell that every A is a B?

This has problems as soon as it hits generics and lifetimes.

That being said, I think a limited version of the feature that disallows the the same type with divergent lifetimes or even all generics would still be useful and well liked.

To skip recreating OOP in Rust, use anyhow instead.

I apologize for this sidebar. I don’t have much to contribute to the technical content. It was an interesting read.

You use, too many, commas, in your, writing. It’s okay to have a long sentence with multiple phrases.

Thanks for sharing your thoughts.
