Officially, Rust's R-cog logo is the symbol of Rust. It is a registered trademark of the Foundation.
But it's a bit boring. Unofficially, Rust has a mascot, in the form of a crab named "Ferris". The crab mascot appears in lots of places, and the Unicode crab emoji U+1F980 is often used by Rust programmers to indicate Rust in text. Unlike the trademarked logo, you can have a bit of fun with such an unofficial symbol, for example Jon Gjengset's "Rust for Rustaceans" book cover has a stylised crab wearing glasses with a laptop apparently addressing a large number of other crabs.

Yeah, I know that, that's why I asked if that's what parent meant, because I can't see why Rust was mentioned there
