Right, thanks. That does look like a PoC of a Rust API. I wanted the
rustdoc output because I find it provides a very uniform and readable
presentation even of an API with no doc comments.
I think maybe a thing I am missing is how you expect this to be used.
Which parts of the system are going to be in Rust. etc.
And that would help explain what "public" means.
I think the answer is probably in this example:
https://patchew.org/QEMU/20210907121943.3498701-1-marcandre.lur...@redhat.com/20210907121943.3498701-30-marcandre.lur...@redhat.com/
but although my C and Rust are both fine, I don't understand qemu well
enough to make sense of it.
... wait, qga is "qemu guest agent" ?
I think I am sort of seeing this use case now. But presuambly there
are other use cases for this QMP/QAPI type bridge stuff.
Sorry to be asking such stupid questions.
Thanks,
Ian.
