In my understanding traits (I guess you mean as defined in Rust?) are more powerful than interfaces in the sense that you can define them for objects from the outside, but I don't see how you could use them to build dynamic-dispatch like functionality? Not an expert on traits at all though. I think traits and interfaces are more supportive of a composition-like programming style, one might call that object-oriented but I still think it misses several key concepts of classical object-oriented languages.
