[lcall]

I think I had found that one, but didn't actually try it. By multiplatform way, I meant avoiding native libraries (sounds like more maintenance and debugging over time) and still being able to run on OpenBSD (or any BSD), linux, windows, and mac, at least.

Edit: yes, I think it does not currently run on OpenBSD, etc. One could contribute that library, but in that case, I'm more inclined to learn Rust and not deal with the JVM at all. Then I also get convenient access to things like pledge() and unveil(), and other OS-specific system calls, when I want. :) I will be grateful, however, for further correction & enlightenment... :)

(Edit2: I have been reading "the book" in Rust, but probably should write a test to confirm that it will make calls to sqlite and pledge() as directly as I think, using the tools I found.)
