Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

        okay, what else can you do in an OOM condition *that makes sense to do*, in pretty much any case?

        Return (or throw, if that's your idiom) the error to the caller, leaving any mutable objects being manipulated in consistent (preferably unmodified) state.

        And 99% of the time the caller will either abort or ignore the error and SIGSEGV anyway.

        N levels back up, maybe. Unless it's stateless/contains no valuable state, or unless it's utter crap, not without first dumping a recovery file of some sort.

        Or you can write rust with nostd, and no allocator (bring your own). But what would you do anyway if you `vec.push(x)` and somehow there isn't enough ram? How would you signal the error in a way that makes sense to the caller of `push`?

        Replying to @das_kube @RichFelker @bofh453

        The push method could return `Ok(())` when it succeeds and `Err(x)` when it fails. Since `Result<T, U>` is marked #[must_use], it forces the caller to handle the error case. Rust as a language is well-suited to writing low-level, robust code. The non-core stdlib is the issue.

        im really thinking like 87% of rust users woulda revolted if they'd had to error-handle every allocation

        Writing correct code is hard. Everyone wants toy languages that let you pretend it's not and paper over everything that could go wrong. *sigh*

        By this logic, Linux, with its pervasive overcommit, is "a complete joke".

        You can turn it off. There may be kernel OOM bugs but with overcommit_ratio sufficiently low you shouldn't be able to hit them.

        Yeah unfortunately people keep forgetting embedded where OOM can happen during normal operation. But, panic is still better than writing to invalid memory.

        There's official support for avoiding the higher-level runtime / standard library where handling OOM isn't supported. It has a lower-level minimal standard library: https://doc.rust-lang.org/core/index.html  It's unfortunate that more of the stdlib wasn't made available in this form though.

        There's a small but active 3rd party ecosystem based around libcore rather than libstd. Not everything using Rust uses the standard liballoc / libstd unable to handle OOM errors. For example, kernel projects and those writing a library with C ABI presumably wouldn't use it.

        Rust originally wasn't aimed at being suitable for such a low-level niche. It rapidly changed leading up to 1.0. It moved away from garbage collection, segmented stacks, M:N threading, etc. Evolution was cut short by them wanting to rush out 1.0 with guaranteed compatibility.

        Low-level / robust usage of Rust is officially supported, but it's essentially a separate ecosystem and a lot of the higher-level library ecosystem would need to be ported / adapted. The language is very well-suited to low-level work. Most of the library ecosystem really isn't.

        this is just lazy engineering. i guess it's the c++ situation all over again if you're designing a system programming language from scratch i wish you'd at least get this part right
