Why iheritance is bad? Iheritance is very useful in object programming, while in Rust decided to aggregate instead of inheritance.

[image] Composition over inheritance Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should achieve polymorphic behavior and code reuse by their composition (by containing instances of other classes that impleme…

[image] AndrzejB: Why iheritance is bad? Iheritance is very useful in object programming, while in Rust decided to aggregate instead of inheritance. I don't think inheritance is bad. Like any other language feature it can be used inappropriately. It's a wonderful thing when used correctly. M…

Note that one advantage that structs with traits have over inheritance is that if you have an object of type A for some struct or enum A, the compiler knows that you're dealing with the type A and not some subclass. This means that function calls can just be a direct call to the correct function ins…

Inheritance isn't bad, it just is. What you do with it is your problem. I started writing a really long post here but it was far too long-winded for your simple question. Maybe I'll make a blog some day. Basically, Rust provides three features -- enums, traits, and generics -- that collectively sol…

If used properly, it's fine. The problem is that it's harder to use properly than it seems. If you want to make a subclass that doesn't have all of the behaviors and properties of the base class, you shouldn't be using inheritance: [image] Liskov substitution principle The Liskov substit…

Maybe better soltution than inheritance would be mixins known from Magik based on Smalltalk?

[image] ZiCog: Now a days hearing a lot about moving away from OOP for performance reasons. With more data centric designs. That is rather outside my experience. Minor note: It's not just for performance reasons -- depending on what you do, it may lead to more maintainable code as well. Thi…

Awesome video! I love it. To add to it, isn't using libraries at all at odds with the idea of encapsulation?
