@roadriverrail @thephd unfortunately, i don’t expect we’ll see a Rust ABI anytime soon.
Here’s a superb article explaining the work Swift (Apple) invested into implementing features to make an ABI *possible*

I just don’t see Rust having either the use-case or sponsorship to implement anything similar.
(maybe Microsoft if they fully commit? I won’t bet on it)
