Added Jan from Pengutronix since
Richard said he might be interested
in the rust in oe-core work.
See below if you want to kick the tires
using my poky-contrib branch.

I was stuck on the librsvg build error for a while so

The hardest part may be getting the crate fetcher into bitbake in an
I haven't yet looked into how the cargo fetcher works.
The cargo bitbake tool can generate bitbake recipes from a toml
It certainly lists all the crates in the generated recipe's
and it looks like they are fetched during do_fetch but I haven't
done the fetch and then disabled the network to be sure yet.
I'm all in favour too, as long as it really is sorted to be a first
That's why I specifically CCd Randy: he's done some work towards this, so I was hoping for some kind of current update or maybe remaining items where help is needed.
Yes, I've been mulling that over as well.
Rust and to a certain extent go has a bit different dynamics, where
the language tools are pretty much inherently cross compilers. they
provide easy installers and updaters for tools
and they release very often, they also have their own package
management systems, the programs are quite standalone in the ( like
static programs) so there is not much need for them
from system. end-users update compilers very often than not they are
using the latest compilers due to the above reasons.
these are real concerns when you consider timed releases schedules
like yocto and now we have LTS too.
Please could do app development using their
distro's rust or the 'rustup' toolchain by specifying
$ cargo build --target TRIPLE
and then for production releases, use bitbake.
I agree with Richard's sentiment that we need robust fetcher
integration as a starting point and perhaps full knowledge of
dependency management to offer a compelling solution. I would like to
see it used when in core and we need answers for the above topics,
currently, meta-rust e.g. follows a release cadence of its own which
is good fit for developers, maybe not as much for release
After months of neglect, I did update the merge of
meta-rust to oe-core over the long weekend. Of course now
different things are broken than before!

I'll get things in somewhat better order and push what I have
or wherever so that other people can join in the fun or see
what's going on.
Well, it's not in 'better order' but it builds and runs
rust-hello-world and ripgrep.
I've pushed what I have to poky-contrib in case anyone wants to
the librsvg build over the weekend! :)

The latest error when doing 'bitbake librsvg' on the newer

but bitbake rust-hello-world or bitbake ripgrep works fine.
After I (we?) get librsvg to build again, I believe there were
problems with gstreamer as well.
