Is it possible to cause a memory leak in Rust?

Yes, leaking memory in Rust is as easy as calling the std::mem::forget function.

Memory leak can happens also if you create a cycle of shared references:

Memory could also be leaked by std::rc::Rc or Arc, through reference cycles.

All those examples show that a memory leak does not offend the memory safety guaranteed by Rust. However, it is safe to assume that in Rust, you do not have any memory leak, unless you do a very specific thing.
