> yes you are right that we do not need this struct. instead, we can just pass arguments around. then, instead of a struct, we will need to pass 4 arguments around. Also, the |offset| and |root| are only needed if the |rule| is CanNotCrossEditingBoundary.

Could you elaborate on why we need those 4 arguments?

RenderedPosition is meant to provide abstraction around renderers and inline boxes in editing code. If the code touches inline boxes and/or talks on render tree, then it's a strong indication that it should belong in RenderedPosition.
