> You literally don't leak memory in safe rust, that is kinda of the whole point. That's a common misconception. Safe Rust prevents use-after-free, double-free, accessing uninitialized memory, (an extremely constrained form of) data races, and a number of other things. It doesn't give a rip about leaks beyond a best effort. Leaks do not violate memory safety. Part of the reason it doesn't care is because it's hard to infer your intent. A common class of bug is accidentally boxing a reference to something you'd like to drop (this and similar flaws afflicted Actix till at least the 3.0 release). Rust confirms you don't have UAF and that you don't drop the data before you're done with it, but by accidentally writing it so that it lives nearly forever that drop is never executed. Rust, similarly, makes no guarantees about drop's behavior at any point in time (other than that it won't be executed to soon and should usually attempt to be executed eventually), but definitely not near program shutdown or similar. It's especially dangerous because a huge fraction of programs run correctly regardless most of the time.
