Interoperability Between Scala and Rust

This repository demonstrates how to achieve interoperability between Scala and Rust by integrating Rust code as a shared library within a Scala Native project.

Setup

Rust Module

1. Navigate to the rust-module directory.
2. Build the Rust code into a shared library (dynamic library) using Cargo:

cd rust-module
cargo build --release

In the root

1. Run the following command to specify additional directories to search for shared libraries at runtime (required on Linux):

export LD_LIBRARY_PATH=${PWD}/rust-module/target/release/:$LD_LIBRARY_PATH

Running the Application

Run app:

sbt scalaModule/run

Run binary:

sbt nativeLink
SCALA_VERSION=$(sbt "scalaVersion" | tail -1 | awk '{print $NF}')
./scala-module/target/scala-$SCALA_VERSION/scalamodule

Run test:

sbt test
