That's already explicitly covered by their trademark policy.

> Using the Rust trademarks in the names of non-commercial products like RustPostgres or Rustymine, or in the name of code repositories in e.g. GitHub, is allowed when referring to use with or suitability for the Rust programming language. Such uses may also include the Rust logo, even in modified form. For commercial products (including crowdfunded or sponsored ones), please check in with us to ensure your use does not appear official.

> They probably weren't trying to deceive anyone
