Thanks for the free lesson, Random Internet Stranger. I appreciate it. Unfortunately, the cognitive dissonance you give me is just too much to bare. Your wisdom is clearly beyond reproach, and so therefore Rust cannot be a systems language since it has panics. Yet, I and many others use Rust for systems programming. My brain might explode from the contradiction!

> therefore Rust cannot be a systems language since it has panics

Or, the obvious alternative that I was trying to point out: your analysis is wrong, and therefore, assuming the language is not useless, there must be a proper alternative to "panics everywhere" * that you are not accounting for !

https://lkml.org/lkml/2021/4/14/1099

* This is just to explicitly write the phrase again before it is (again) twisted as calling for a strict prohibition of all non-terminating conditions or some other childish nonsense.

Even unwinding panics (which are exceptions in all but name) can be an alternative, and Rust does support them.

Cool, good thing I didn't say to panic everywhere.

That lkml post has zero relevance here. He's asking for fallible allocations. Which is totally reasonable.

Serious question: did you read the entire blog? If so, can you specifically point out passages you disagree with and why?

EDIT: And seriously, I started out this conversation with a serious comment asking you to elaborate on what you meant by asking something very concrete: how would you change the code example in my blog to conform to your view? You decided to flippantly respond with a non-answer in the first place. Why not go back to the original question I asked and give a real answer? If you don't know Rust, then use pseudo code. We're talking about a dozen lines here. It shouldn't take long.
