This is also what I attempted, and as I remember it didn't work either, though to be honest I was really worn out fighting the obscure compiler errors by that point, I might have missed a sigil somewhere.
I spent good solid 30min trying to understand why defining and not defining my constructor was causing issues, to realize that the constructor error was actually a previous error, somewhere above the constructor.
Rust, also notes where and how you created an infinite loop.
Your compile error is likely because you use references instead of pointers. Reference as a class member is really hard to get right because it can be initialized only once, and cannot be copied or moved.
