In this next1 post of my series explaining how Rust is better off without Object-Oriented Programming, I discuss the last and (in my opinion) the weirdest of OOP’s 3 traditional pillars. It’s not encapsulation, a great idea which exists in some form in every modern programming language, just OOP does it oddly. It’s not polymorphism, also a great idea that OOP puts too many restrictions on, and that Rust borrows a better design for from Haskell (with syntax from C++).
