Java bindings

codemp's Java bindings are implemented using the JNI.

On the Rust side, all Java-related code is gated behind the java feature, and is implemented usingjni-rs. Unlike other languages, Java requires glue code on both sides: as a result, a Java component is necessary.

Building

This is a Gradle project: building requires having both Gradle and Cargo installed, as well as the JDK (any non-abandoned version). Once you have all the requirements, building is as simple as running gradle build: the output is going to be a JAR under build/libs, which you can import into your classpath with your IDE of choice.

Development

The Java bindings have no known major quirk. However, here are a list of facts that are useful to know when developing with these:

  • Memory management is entirely delegated to the JVM's garbage collector.
    • A more elegant solution than Object.finalize(), who is deprecated in newer Java versions, may be coming eventually.
  • Exceptions coming from the native side have generally been made checked to imitate Rust's philosophy with Result.
    • JNIExceptions are however unchecked: there is nothing you can do to recover from them, as they usually represent a severe error in the glue code. If they arise, it's probably a bug.
