Supercharge Your Java Projects with Rust: A Practical JNI Integration Guide

This article explores integrating Rust code into Java projects to boost performance and efficiency. It details using JNI (Java Native Interface), handling memory management, logging, and asynchronous calls. The open-source project rust-java-demo showcases packaging platform-specific Rust libraries into a single JAR, unifying logs, and mapping Rust errors to Java exceptions. It also explains using CompletableFuture to handle asynchronous Rust function calls, preventing Java thread blocking.
