Eh. If you don’t know how references work in rust, you’ll struggle to use most of the standard library or any 3rd party crates. And if you can’t pass mutable references to functions or iterators there’s a lot of programs that will be hard to write at all. Performance will be pretty rubbish too. You might be able to write some simple programs, but I wouldn’t say you know rust yet, or could really be productive with the language.
