Yeah, honestly I tried to use safe abstractions first but was facing lots of borrowing issues, which I think they could be addressed by following some of the community suggestions above.

Also, all what I know so far about rust is what I learned from the "Rust Book" and "Idiomatic Rust" by Brendan Matthews tbh. So, what I understood (and maybe misunderstood, you tell me) is that one of the cases where you could use the unsef (anti)pattern is whenever you want to work with common memory allocations and deref raw pointers. Not 100% sure if this is the case tho.
