You can say this for ANY language. Literally any language that can assign a function to be part of some struct could be "OO"... which is basically any language including C. So given the pervading reality, colloquially when we say the term "Object Oriented Language," we are not referring lisp or C or haskell even though all of those language are technically OO. The same can be said for Rust. Rust is NOT OO.
