Catch the panic & unwind, safe program execution continues. Fundamentally impossible in Fil-C.
I also don't think it's that niche a use case. It's one encountered by every web server or web client (scope exception to single connection/request). Or anything involving batch processing, something like "extract the text from these 10k PDFs on disk".
Generally, I think one could want to recover from errors. But error recovery is something that needs to be designed in. You probably don't want to catch all errors, even in a loop handling requests for an application. If your application isn't designed to handle the same kinds of memory access issues as we're talking about here, the whole thing turns into non-existent-apples to non-existent-apples lol.
> All this "rewrite it in rust for safety" just sounds stupid when you can compile your C program completely memory safe.
All of the points about Rust were made in that context, and they've pushed back against it successfully enough that now you're trying to argue from the other side as if it disproves their point. No one here is saying that there's no point in having safer C code or that literally everything needs to get rewritten; they're just pointing out that yes, there is a concrete advantage that something in Rust has over something in C today even with Fil-C available.
