Why is setjmp such a major issue for you? It's a C language feature, not a "real low level to the metal systems programming" requirement.

- CalChris 9y agoIf you are calling C or assembly and there is any sort of processor exception, you need to establish a signal() handler and you will need setjmp/longjmp to re-establish a safe stack frame. Yes, this is a C/assembly thing. But it is also a Linux/BSD/Unix thing. You really cannot call Rust a systems programming language if signal/setjmp/longjmp are not fully supported. It just goes with the territory.
- Rusky 9y agoLinux/BSD/Unix are hardly the only systems programming environments. I'd hesitate even to call them the majority. And for now, there are definitely ways to handle signals using libraries.
- lossolo 9y ago> Linux/BSD/Unix are hardly the only systems programming environments. I'd hesitate even to call them the majority. Do you have any source that can confirm that? Because what you wrote seems really wrong. I see linuxes/bsd/unix EVERYWHERE (Android/iOS/OSX/almost all backend servers etc.)
- Rusky 9y agoI'm thinking of embedded systems and desktop machines- the first tends not to use an OS nearly that big (if any at all), and the second tends to use Windows.
