fn project_reference(r: &MyStruct) -> &Field {
        &r.field
    }

    unsafe fn project_pointer(r: *mut MyStruct) -> *mut Field {
        unsafe { &raw mut (*r).field }
    }

    // The equivalent C code would look like this:
    struct field *project(struct my *r) {
        return &(r->field);
    }

I am a very heavy Rust user. I mostly program in safe Rust while occassionally dipping into unsafe Rust.

IDK, I think Rust should stick with what it is good at and not try to expand into domain that it is clearly not nicely designed for. That is, what if the best way to implement linked list in RUST is via an array of indices and NOT through RefCell or whatever it is? What if Rust will never ever have a sane way to implement linked list. What is so wrong with that? I think there should be a very clean divide between C and Rust. Rust stays in the happy Rust world and C stays on the happy C world.

I am not sure I am excited to see something like this

    unsafe fn project_pointer(r: *mut MyStruct) -> *mut Field {
        unsafe { &raw mut (*r).field }
    }
