> This isn't a problem in Rust because it doesn't have exceptions

Rust does have something similar to exceptions when compiled with "panic=unwind" (the default). It uses the same mechanism as C++ exceptions to unwind the stack (while calling all the necessary destructors), can be caught (std::panic::catch_unwind) and rethrown (std::panic::resume_unwind), and has some of the same concerns as C++ about "exception safety" (mostly within unsafe code - the programmer has to take care to leave the objects in a safe state when it can unwind).

I didn't know that used something akin to exceptions. Still panics aren't as common as exceptions (in D), and still only have to worry about unsafe code (for the most part).
