There were over 200 memory safety violations discovered in rust crates: https://www.infoq.com/news/2021/11/rudra-rust-safety/
Elixir for example, is very safe and guarantees more safety than rust.
So bam, you just introduced memory safety issues into your web API. This is like a C++ dev using C++ and causing memory issues unnecessarily just because they don’t want to use a safe language.
And Elixir has concurrency and memory safety and it’s guaranteed, so no package you import can violate it. Unlike rust, where you can use safe rust and think there’s no violation, but then use a crate and suddenly have memory unsafety and concurrency violations.
These crates worries are wayyy better than normal C++, but they are terrible compared to any actually safe language.
And FFI? As in the Unix extensions? That’s the operating systems calls, not the language. By that logic, python is as dangerous as C++.
It’s crazy how so many people on this thread say rust is the only choice because of memory safety, and are now bending over backwards trying to claim memory safety is no big deal. So much so FFI is now being brought up smh.
