Unable to use circular fixtures

[la10736]

You mean something like #[once] but with a test context instead of static.

Please can you open a new issue with a simple behavior description and provide a simple example where it can be useful.

I guess that what you really mean here is to build the dependency graph to check a circular reference and raise an explicit error.
This is really hard and need some crappy hacking because procedural macro receive just the annotated function and cannot know anything about the context. Anyway procedural macro are executed before module resolving phase so it is quite impossible to cover all cases on procedural macro expansion.

Last chance can be use a recursive function analysis and show them in your IDE but I didn't find anything about this ... just an open ticket on rust-analyzer rust-lang/rust-analyzer#11407

Unfortunately/Fortunately rust is not python and procedural macro are not function decorators.

If you have some ideas on we can handle this let me know.

Thanks for the feedback!

Hmm. yes, it would nice to have. Got the point about procedural macros.

Then what do you think of about adding something like #[once_test]? This could instantiate the fixture once per single test and reuse it in other fixtures. I think it would solve the issue perfectly and add nice feature from pytest world.
