Thanks for the feedback! You're right that describing our usage a bit better might have helped clarify our thinking. For the record: the FullStory product is a session record and replay tool for both web and mobile. We record details about how your users interact with your site or app and you can watch replays of them as well as get analytics across sessions. Privacy is important to us, which you can read about here: https://bionic.fullstory.com/private-by-default-mobile-analy...

The bulk of what we're doing in Rust is data serialization, along with business logic, part of which is a state machine and part of which is applying specific rules to app content. We did have fully native implementations of this in our prototype. Supporting two parallel implementations would be way harder for us than supporting our Rust implementation. It's hard enough to support the code that's platform-specific by necessity!
