Can you post the complete error/terminal output? This is likely a rustc or cargo bug/issue. Try a cargo clean which may resolve things.

I installed an extension called rust-analyzer. When I run this program,everything is fine. But in VS code, there are always errors reported by the extension. It makes me confused, since I don't know whether I code correctly.
Here's the output of the extension:

Did you enable proc-macro support in rust-analyzer, as the link you posted indicates?

I disabled proc-macro just now and The problem was solved. Thank you for your help.
