Nothing breaking has changed in the Bela API since then (it has only been expanded a bit ), so I guess it should just work.
djensenius Or if there is any chance of official Rust support for Bela?
There are no hard and fast rules as to how a language becomes "officially supported" by Bela, but we'd need at least a few users who use it routinely, otherwise there is the risk of:
a) the support breaking, because of API changes, old documentation, etc
b) spending development time on something that benefits no one
None of us on the core team of Bela is a Rust developer, which means we wouldn't be in the position of maintaining it and adding features to it without a significant community contribution and/or interest . A possible pathway towards getting "out of the box" support for Rust on Bela, would be for someone (e.g.: you, and/or @padenot / @andrewcsmith if they have kept using it beyond their great contributions above) should make sure the steps above still work, then come up with at least a minimal set of examples to cover the basics (think something like the "Fundamentals" examples we currently provide for C++, or the examples for Supercollider and Csound). In the process, hopefully the functionalities will receive further test and possibly additions.
I am happy to help every step of the way with integration, but I'd rather not to have to write anything on the Rust side (because I don't know how to!).
As a side note, a "success story": Supercollider support was added with community contribution where I took part of the integration, and I still maintain it today. We are a few revisions behind the official repo, but now looking at merge upstream in a future not too far away. In the process, I have - to this day - written more lines of Supercollider C++ source code than Supercollider programs.
