Description
Problem
Just a small thing I noticed while reviewing another PR.
Summary
The method
element_typesreturnsArc. There's a comment inelement_sizethat says it's equivalent toelement_types().len()but without consumingselfso I wondered why it was consuming self. Given that the method returnsArcwe can cheaply clone a reference to Arc and return that. Then this avoids a couple of clones before calling this method. It probably doesn't have any effect on anything but now there's no need to unnecessarily consumeself.Additional Context
