Bug Report Checklist

• Have you provided a full/minimal spec to reproduce the issue?
• Have you validated the input using an OpenAPI validator (example)?

The input is valid, but contains a circular reference.

• Have you tested with the latest master to confirm the issue still exists?

No, only 7.2.0. Is there a way to make openapi-generator-cli use the master version???

EDIT: Marking this done because the underlying code issue still exists on master (#17368)

• Have you searched for related issues/PRs?
• What's the actual output vs expected output?
• [Optional] Sponsorship to speed up the bug fix or feature request (example)

Suggest a fix

Stop considering "ref" a reserved word.

Start with the failure path in DefaultCodegen.java and the Rust generator entry point identified by AbstractRustCodegen, then review related issue #17368 because the report says the underlying problem moved there. Re-run the Bitbucket OpenAPI generation command and consider the issue complete only when the valid specification generates successfully for Rust without the reserved-word failure.
