#[serial(crate = ...)] parameter

#[serial_test(crate = wrapper::__derive_refs::serial)]

This is for proc-macros generating #[serial_test] annotations: they should rely on reexports of serial crate.

I haven't seen this problem before. Can you provide a demo of the problem and why the current setup doesn't enable things?

[stepancheg]

This is how serde is doing it for example: https://serde.rs/container-attrs.html#crate

Use case is this: I'm developing a macro like #[my_test_utils::my_test] in a crate my_test_utils. It should expand to:

#[serial_test::serial]
#[test]
fn xxx() {
  // custom my test logic...
  ...
}

However, serial_test may not be imported where this my_test_utils crate is imported (or imported, but wrong version).

#[my_test] could be expanded instead into

#[my_test_utils::__derive_refs::serial_test::serial(crate = my_test_utils::__derive_refs::serial_test)]
#[test]
fn xxx() {
  // custom init...
  ...
}

so that when #[serial] ireferences serial_test crate functions, it references them as my_test_utils::__derive_refs::serial_test::xxx instead of serial_test::xxx.

Please let me know, if this explanation does not help.

Yeah, it makes more sense now. I'm busy with a whole bunch of things at the moment, and won't get to this anytime soon. OTOH, if you're able to provide a PR for this, I'm happy to review.
