> And if you need to write those things, it's not like it's impossible, you just need to drop down to unsafe rust, and ideally figure out some safe way to expose that API.
I'm sure you know this already, but for the people reading this: first of all "unsafe" is a very rare, and it's only "less safe" more than fully "unsafe"; ie it's still safer than C++.
And the second thing is that, often you don't have to drop into unsafe Rust, it's possible to achieve most stuff without it, but might incur a small performance cost (idk if some of those can be optimised away by compilers or not).
