uniffi-rs VS flutter_rust_bridge

On my youtube series "Growing up Rust", I'm building a personal CRM in Rust with a Swift frontend. I'm using CQRS and an event-driven architecture with the least amount of swift as possible. I'm using UniFFI to generate the bindings for swift (and in this example python)

Not officially. We currently have bindings for rust, python, golang and swift.

These were the most asked for bindings (python for ml, golang for networking and swift for ios apps).

We are using uniffi https://mozilla.github.io/uniffi-rs/

Would you need C or C++ bindings?

An alternative is metacall. The example in the readme is about calling Python from Javascript, but it also works with other languages, like Ruby, C#, Java, and other languages

https://github.com/metacall/core

List of supported languages here https://github.com/metacall/core/blob/develop/docs/README.md...

In the future, maybe webidl (or extensions of it) will bring interoperability between languages too. At the moment there is https://mozilla.github.io/uniffi-rs/ for interoperability between Rust and a number of languages (basically the ones mozilla needs: Swift, Kotlin, Javascript)

The tooling for the first kind -- calling Rust from another language -- is a bit less developed, and tends to rely on code generation that doesn't necessarily produce a natural C API. cbindgen, uniffi, cxx, and Diplomat all take this course.

Mozilla's uniffi-rs is really good. You write a common IDL and the bindings are generated automatically.

At Mozilla we built a multi-language bindings generator: https://github.com/mozilla/uniffi-rs/

Is there a connection with Mozilla UniFFI ?

Rust <> Swift/ Kotlin works very well with uniffi-rs by Mozilla: https://github.com/mozilla/uniffi-rs

Use some sort of executable file, like webassembly. I've seen extism which is really cool. Though theres no dart port for it or a dart package, i think something could be done via flutter_rust_brige. This will allow people to use the languages supported via extism (js, go, rust, zig, cpp etc) to their full potential and have the language's ecosystem available and they can just compile the plugin to a wasm file and use it in the app. Downsides would be ig using that rust package in dart since flutter_rust_bridge does have some amount of complexity. And that for example, two plugins both written in say for example js, depend on some sort of http package, and both plugins load the same package twice in their respective wasm files. ig plugin files would be more larger in the end.

Not a Flutter Dev, but have you tried 'flutter_rust_bridge' [0]. Seems provide some interop between flutter and rust and looks like a popular and active project. I'm native mobile dev and just curious about this kind of interop myself. If it's seamless then looks like good balance to do mobile front-end in flutter and mobile backend in rust.

This template is primarily built using the flutter_rust_bridge library. It also incorporates several popular packages and modifications into the default Flutter template, ensuring optimal development process. It has been designed with future scalability and performance in mind.

If you want example code, the flutter_rust_bridge uses a webworker pool with shared memory on the web to multithread the execution.

There's also the thing that flutter_rust_bridge is currently broken for web development. I have a PR open, but it's running into weird issues with the CI and so can't be merged.

For reference, https://github.com/fzyzcjy/flutter_rust_bridge. And dart is a really nice language too, my only real gripe is that I'm no longer used to [type] [variable] over [variable]: [type]

It appears that this is indeed what was happening. The issue has now been fixed in the template.
