avoid conflicts with other macros

[Siceberg]

The code changed in this PR is to avoid conflicts with other macros like in oso-diesel2-conflict-demo.

Since I'm a beginner in Rust, not very familiar with macros, and I'm in a place where using internet resources is not very convenient, I'm not sure if this is a better solution. If you guys have other better ideas please let me know, thanks.

If this is not a correct solution, I hope to promote Oso to solve related problems as soon as possible through this PR
