Your rustc version is very old compared to the rust-analyzer releases so its likely to fail because of that given the error is within a standard library macro. Either upgrade your rust toolchain or downgrade your rust-analyzer, we generally dont support more than the ~2 latest stable releases for a given rust-analyzer version

I also have this issue on the latest version of rust / nightly release of rust-analyzer.

Cargo check / build reports no errors and if i restart rust analyzer the error disappears but then will reappear after some time.

I suspect its something to do with my macro, ill try make a smaller example

My problem has been solved by updating the rust version, suggested by the comment of Veykril. You can open a new issue providing details of your environment. That's more accurate and convenient. Thanks.
