A trivial example of how to call Rust code from JRuby. The Rust code is compiled to a shared library and loaded by the JVM. JNI is used to call the Rust code from Java. JRuby loads the Java library and executes the bytecode on the JVM.

A Dockerfile is included to build a container with all the necessary dependencies. To build the container, run:

docker run -it -v .:/app jruby_experiment

To run the example, execute the following command in the container:

./build_and_run.sh

This will compile the Rust library, build the Java library, and run the JRuby script.
