2. (object-oriented programming) An uninstantiable collection of methods that provides functionality to a class by using the class’s own interface.

   Traits are somewhat between an interface and a mixin, as an interface contains only method signatures, while a trait includes also the full method definitions. On the other hand, mixins include method definitions, but they can also carry state through attributes, while traits usually don't.
