Zerokit can be succesfully compilled to mobile architectures with rustup or https://github.com/cross-rs/cross, but using this library would still require some dev work, as described in these links:

• https://mozilla.github.io/firefox-browser-architecture/experiments/2017-09-21-rust-on-android.html
• https://mozilla.github.io/firefox-browser-architecture/experiments/2017-09-06-rust-on-ios.html

In golang, we have gomobile which simplifies this work. We should look for a similar tool for rust projects or consider writing a script that would generate a .aar file for Android with the common architectures (x86_64, x86, armeabi-v7a and arm64-v8a) and a .xcframework for ios (ios-arm64 and ios-arm64_x86_64-simulator)
