About this package

Mangle Rust functions for use with JNI

Rust function mangler for JNI

The jni-mangle crate provides proc macros for working with Rust functions that are called from Java through JNI.

The main purpose of this crate is to turn rust functions that might look like this:

#[no_mangle]
#[allow(non_snake_case)]
pub extern "system" fn Java_com_example_Example_addTwoNumbers(a: i32, b: i32) -> i32 {
   a + b    
}

Into something a little more readable:

use jni_mangle::mangle;

#[mangle(package="com.example", class="Example", method="addTwoNumbers")]
pub fn add_two_numbers(a: i32, b: i32) -> i32 {
   a + b    
}
