Safe rust is a turing complete language. That implies that it is possible to build an emulator for any other programming language in safe rust. That emulated language and programs running on it can have memory-safety issues, even if the emulator itself cannot be corrupted.

When writing such an emulator the natural way to set up the memory is to use an array, and the natural way to implement pointers is indices into that array. In other words, this pattern is part-ways there to creating an emulator with internal safety issues.

However guaranteeing that any corruption will be contained to the array is certainly a lot better than nothing.
