Thank you. I'll read the policy again more carefully.

The case is that, I include the Rust source code, but since the CRAN's
Windows & macOS machines don't have the Rust compiler installed, there's no
choice but to download the pre-compiled binary (other than downloading the
Rust compiler).

Thanks, I already responded with what I wrote above, so I hope I can get
the reply.
But, since the CRAN team might be on vacation now, I wanted to get some
advice on this mailing list.
Thanks for your help!
Best,
Yutani
