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.
