Request: Help test native `offset_of!` macro

[joshlf]

As part of rust-lang/rust#111839, we're working to ensure that crates in the ecosystem such as yours work with the offset_of! macro before it's stabilized. I tried to run your tests locally, but ran into issues with my setup, and tried putting up a PR so that your CI tests would run, but it appears that your tests only run on stable, and the test I'm trying to run requires the nightly compiler.

Would someone who already has a local setup configured be able to run the following command (or a variant of it as needed) and confirm that the tests pass?

$ cd crates/virtio-queue
$ cargo +nightly test --features memoffset/unstable_offset_of

See this comment for more details on what we're trying to test. Thanks!

@joshlf by running cargo +nightly test --features memoffset/unstable_offset_of in the root dir all the tests pass.

[joshlf]

Thanks! Does that have the effect of testing crates/virtio-queue too?

[epilys]

@joshlf yes:

% cargo +nightly test --features memoffset/unstable_offset_of --all-features -p virtio-queue

Great, thanks so much!
