Other than the `|var|` syntax in closures, I can't think of a single way Rust looks like Ruby. I mean that seriously, there is almost no other similarities.

Don't forget expressions and block expressions, and all of the Ruby-esque syntax sugar around them. How expressions work with functional methods.
I write a lot of chains with block expressions that almost look 1:1 with Ruby.

There's definitely some Ruby influence (closures syntax in particulary), but I think I'd argue that Rust syntax is closer to JavaScript/TypeScript than anything else.
