Hello there!
I would love it if you could drop in a comment about this code. What can I change to make a better API and/or more accurate implementation of the mathematical type? I uploaded it as a gist.
Thank you for your time!
scalar / vector division doesn’t make much sense in terms of (standard) mathematical notation. Maybe just skip that part, of if you need the functionality of element-wise multiplicative inversion for some other use, consider using a descriptively named method instead.
To be clear, the other division, vector / scalar, is reasonable in my opinion.

Thank you for your input! I made a revision to my code to fix that.
Given that this is a small Copy type, it would seem reasonable to me to make the non-self argument of fn dot a by-value argument – instead of by-reference – too. I see you already changed the &self itself to self, anyways.

I have clippy to thank for that one! 
In your opinion, would it make sense to continue passing self by value when I make types with more dimensions? Would it impact the performance in any significant way?
