There are many more macros. We have already used some of them, such as the cfg!() and vec![] macros. You can also cause an explicit compile error with the compile_error!("message") macro, or use the file!(), line!(), and column!() macros to get the current position in the code, or even the module_path!() macro to get the current module.

If you want to know more, open the standard library documentation by running rustup doc --open and check out the rest of the macros there.
