This makes me want to write a function for you to add to numbers where the variables are leftumber and rightnumber, instead of x and y.
if "left" and "right" were relevant for addition, they would indeed be better names
Are you against using a single letter variable like e for element in iterating over things?
yes
To each their own. But man imagine if you have a collection of stuff that has a large name, and then having to figure out a short name other than e when iterating. I hope you're not iterating over chemical names 😬
No need to be over-descriptive. Anything at all more specific than
ewill probably be a better nameImplementing add (and other math operations) in rust for your types has the type signature self and rhs (right hand side).
Lhs and rhs are much better than x and y
In what way? If you encountered a function that had x and y which just added them together, that's not readable enough?
Well in a vacuum yes sure, you're right, but in practice there's always some context. x and y could be referring to axes, where an addition makes little sense. However lhs and rhs make more sense if you're overloading an operator
