I don't know enough about Rust to say. If it doesn't have the concept of a 'fancy pointer' then I assume no, you'd have to essentially reproduce what boost::interprocess does.

I'm still learning Rust, but iiuc you could do this by creating an OffsetPtr type that implements the Deref trait (https://doc.rust-lang.org/std/ops/trait.Deref.html). This is exactly a "fancy pointer" as you describe.
