The possibility of segfaults is kind of a given though. I mean the whole point of foreign interfaces is to reuse existing C code. The pinning functions just expose the manual C resource management that programmers would have to deal with if they were writing C. You just turn off the automatic resource management for the objects involved so you can do it yourself, running the risk of leaking those resources. The only viable way to escape all this is to rewrite the software in the host language. A worthy goal but I don't see anyone signing up for that herculean task outside the Rust community.
