A helper macro for safe Java-Rust interop that "catches" Rust panics and rethrows them as Java exceptions.

Getting Started

Add catch_panic as a dependency to your Cargo.toml:

catch_panic = "1.0.0"

Usage

Attach #[catch_panic] to a JNI callback to have panics converted into RuntimeExceptions:

use jni::JNIEnv;
use catch_panic::catch_panic;

#[no_mangle]
#[catch_panic]
pub extern "C" fn Java_com_example_Example_panic(_env: JNIEnv) {
    panic!("everything is not fine");
}
