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).
- exiled13 7y agoI 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).
