When compiling the zbus_macros crate, I get this error and it doesn't compile properly. It's pulled from crates.io so it should be the newest version.

Looks like your syn crate might be super old? This method was added 5 years ago.

Actually, it was added just last year. I'll bump the syn crate requirement. Thanks for reporting.

BTW, it's recommended to use zbus_macros through zbus instead of using it directly. It won't help with this issue but just a general tip.
