Calling Rust

We can now call this from a C binary:

interoperability/rust/libanalyze/analyze.h

#ifndef ANALYZE_H #define ANALYZE_H void analyze_numbers(int x, int y); #endif

interoperability/rust/analyze/main.c

#include "analyze.h" int main() { analyze_numbers(10, 20); analyze_numbers(123, 123); return 0; }

interoperability/rust/analyze/Android.bp

cc_binary { name: "analyze_numbers", srcs: ["main.c"], static_libs: ["libanalyze_ffi"], }

Build, push, and run the binary on your device:

m analyze_numbers adb push "$ANDROID_PRODUCT_OUT/system/bin/analyze_numbers" /data/local/tmp adb shell /data/local/tmp/analyze_numbers
