looks very good and just thinking out loud... wouldn't it be cool if you could use Rust from JVM languages? How would that even look like? Is it even remotely possible? (I don't know TBH)

I really don't know. I have no experience with Rust...

I used it a bit last year. you have a borrow checker that makes sure that there are no leaks. but no idea what it really doies

Anyway, the point of Clojure-CPP is to access a vast ecosystem of unavoidable native mega-libraries (such as MKL or CUDA) when writing your own alternative is either not possible or not very viable. I'm not sure how many such Rust libraries are available (and needed from Clojure).

very true... it was just a thought I had, nothing more. and great work on your library. 👍

there are crates to call rust libs from java - https://docs.rs/jni/latest/jni/ it is totaly possible to use from clojure

here's an example of rust jni crate with clojure https://github.com/borkdude/clojure-rust-graalvm

If you're just trying to wrap a shared library (built with c, c++, or rust), then IMO https://github.com/phronmophobic/clong is very effective. The cool thing about javacpp is that it handles one of the more annoying parts about working with native libraries which is building and distributing them as maven artifacts.

As long as the native library satisfies the c ABI, you can usually get up and running with:

(def libz
  (com.sun.jna.NativeLibrary/getInstance "z"))

(def api (clong/easy-api "/opt/local/include/zlib.h"))

(gen/def-api libz api)

(zlibVersion) ;; "1.2.11"
