7.1.5 从 C 调用 Rust
现在可以从 C 二进制调用它了：
interoperability/rust/libanalyze/analyze.h

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

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

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

在设备上构建、推送并运行该二进制：

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