Likely a case where Google figured out which one you meant through the telemetry of what you clicked on and how you refined your search, now that personalization is automatic. In my case, I get four regular results, which are the financial standard, the programming language, the wikipedia page for the programming language, and an ISP; then I get a "top stories" block that is all about the singer.

More tricky for the sibling comment with Rust, where either one could be valid.
