[Rust] There is no check for allocation failure

[asfimport]

Reported by bluss on Github:

"What I can see, there is no check for allocation success, so any buffer can be created with a null pointer, which leads to soundness problems in most methods. Best look into using std::alloc::handle_alloc_error or alternatives. (This problem means that the mutablebuffer is not a safe abstraction, and it should preferably not be exposed as public API like this.)"
