Depends on if you're coding for critical infrastructure (i.e. - electrical grid), or writing a high performance video game that can run on older hardware.
We should absolutely have specific licenses like Civil Engineers do for computer infrastructure that is required for any software written for specific purposes. It would be a nightmare to implement, but at some point, it's going to be needed.
Unless it's some really exotic platform, I'd honestly still say no. Rust has shown that memory safety and performance doesn't have to be a tradeoff. You can have both.
But sure, if whatever you're targeting doesn't have a Rust compiler, then of course you have no choice. But those are extremely rare cases these days I'd say.
Can we stop pretending Rust doesn't take performance trade-offs? Of course if you compare it one to one its roughly the same, since it's compiled. But Optimizing memory for cache hits becomes a lot more difficult in Rust, to the point where you have to use unsafe. And unsafe Rust has more undefined behavior than C. In my opinion C is more safe than unsafe Rust.
If you want normal performance its a good Language, but once you need to Optimize memory, which is usually the bottleneck, You are out of luck.
Why is this?
