As stated in the Overview, this library and tutorial does not cover how to ship a Rust library on mobile, but how to generate bindings for it, so this section will only cover that.
First, make sure you have installed all the prerequisites - particularly,
uniffi-bindgen (or alternatively, understanding how to run it from the source tree)
uniffi-bindgen generate src/math.udl --language kotlin
then have a look at
uniffi-bindgen generate src/math.udl --language swift
then check out
Note that these commands could be integrated as part of your gradle/XCode build process.
This is it, you have an MVP integration of UniFFI in your project.
