Could possibly tweak ci to catch this in future

Run a pipeline with ffi only?

[tustvold]

Yeah we already have some cargo check jobs for this purpose, could possibly add a few more variants. Depends when we eventually split the crate, feature flags are a bit of a hack 😅

[viirya]

I see. 😄

Yea, I will add a few more variants including ffi in another PR.

[viirya]

Thanks.
