Yes. It’s pretty common to need to interact with existing APIs or libraries that only have a c interface. Fortunately, rust is good at that. Unfortunately, it’s impossible to do without unsafe code. You can wrap libraries in safe wrappers, or if you’re lucky someone has a wrapper you can use… …but I’ve heard it several times for this reason, especially in shops that have existing internal code bases (Ie. 0% chance of an existing safe wrapper) and want to incrementally adopt rust. Never heard someone say it’s because of perf tho; that sounds like a strawman argument to me; if your code is seriously too slow because of the bounds checking you’re doing something crazy and probably want to be using a gpu instead. It’s usually io bound, and unsafe code doesn’t fix that.
