-  - `safe_mode::Bool`: whether to run additional checks to catch errors early. While this is
-    on by default to ensure that users are aware of this option, you should generally turn
-    it off for actual use, as it has substantial performance implications.
-    If you encounter a problem with using Tapir (it fails to differentiate a function, or
-    something truly nasty like a segfault occurs), then you should try switching `safe_mode`
-    on and look at what happens. Often errors are caught earlier and the error messages are
-    more useful.
