Recuperar Usb Sin Formatear

I have seen many topics about this, but I still not understand how to make it . Install from pkg install rust can works, but the version is too low. Rustup is not support aarch64-linux-android host triple, I have attempted many ways such as using aarch64-unknown-linux-gnu and compile from source but none of which works. So is there a way to use Rust on Android?
(Add: I'm not mean to generate APK, but just the binary executable file)
