similar to: [PATCH nbdkit] Add support for writing plugins in Rust.

There are few more things that could be cleaned up related to the coding style and other things, like explicitly specifying the abi style after "extern" (i.e. `extern "C" fn` instead of `extern fn`), but since those are configurable in rustfmt config, I'm not sure whether the config needs to be added or complying with the defaults should be the priority. But this was just

Still not working, but I took the latest patch and: - rebased it against libnbd 1.0 - fixed it so it handles new args and cbargs The generator now runs without warnings. This patch doesn't handle optargs at all. In C these are converted to non-optional parameter. Rust doesn't (AFAIK) have optional or labelled arguments unfortunately. Rich.

> Is this just trying if the guestfs can be linked with? Yes. In OCaml bindings, there is the corresponding test( https://github.com/libguestfs/libguestfs/blob/master/ocaml/t/guestfs_010_load.ml). I just mimicked it. If it is not required, I will remove it. divided the generated files and handmade files in rust/src/ directory. I'll send this fixed patch to this mailing list. I'm not

Similar to what I just did for OCaml (this IS an API break, requiring recompilation of any existing Rust plugin), and done because I want to add fast_zero support to both languages as part of my upcoming fast zero series. Figuring out how to get extents working was hard enough that I punted that, still. Eric Blake (2): rust: Implement can_cache rust: Add support for dynamic .thread_model

Hi Hiroyuki, sorry for the late reply. Most of the work is definitely nice! There are few notes below, although they are not big issues. I will check this patch once more on monday, especially the rust parts. Otherwise, I'd say that we are close to merging this :) On Tuesday, 23 July 2019 10:37:17 CEST Hiroyuki Katsura wrote: > From: Hiroyuki_Katsura

I fixed the patch I submitted before based on comments, and there are some commits which are merged or divided. So, I will re-send all the patches. Regards, Hiroyuki Katsura

I found a bug in the bindings, so I fixed it. I'm sorry about sending you the patch many times.

Patch 9 is a kind of dumping ground of all kinds of stuff. It may be better to spend some time with git rebase -i trying to work this into more coherent patches.

This is just a basic ugly support, not meant to be pushed (at least for now). There is quite a lot missing, but there is an example which shows that it really works. And valgrind reports that all allocations were freed. The way the code is generated is also not nice, I wish there was more code actually written in some files and not generated by the generator (as much hard-coded static strings as

I fixed based on comments.

I originally meant to post only the "vector.h" patch, but then (independently) nbdkit wouldn't build. Hence the other (rust plugin) patch.

I managed to get a build of the async Rust handle compiling on FreeBSD (although the cirrus CI appears to not actually run 'make check' on non-Linux machines, at least when run on my fork): https://gitlab.com/ebblake/libnbd/-/jobs/4985192286 However, I'd really like Tage's review on patch 2 to see if my Rust makes sense.
