Exported rstest_reuse template cannot be defined at the top level about rstest HOT 5 CLOSED

Ok, I decided for a breaking change and stop to support the #[macro_use]. Now I used the same approach used by macro-vis and hide the original macro by a random name.

Export at the root now works and I avoided to introduce a new wired syntax like #[no_local]. You can also export a template from a sub module but you should point it with the full path or reexport it at the root.

Playing with macros is tricky and I cannot recognize that the template is in a module or not in the procedural macro so I cannot change the behavior of #[export] annotation to fit this possibility. The only way to implement this behavior that I can see is to introduce a #[no_local] annotation that can be used to remove pub(crate) use #macro_name as #macro_name; trick used to have locally templates.

I see, that's a tricky situation. There are workarounds floating around like macro-vis and macro-pub which are based on name mangling. There are some caveats listed but overall looks like an improvement (both to avoid this particular issue and to allow the generated test case to be exported from the module namespace)

I hope to publish the new version for the end of the week....
