I'm not sure where this meme on HN that Rust isn't OO comes from but it's based on a definition of OO that is almost never applied by day to day programmers and it's disagreed with by a fair number of language theory people. Rust has encapsulation, message passing in the smalltalk/OO sense, and polymorphism. It does this through objects with attached methods, and traits. In every way that actually matters to a working programmer Rust is OO.
