google-cloud-rs VS tonic

Addendum: looking again at the Gcloud Rust SDK, I remember why I don't use it. It doesn't support streaming bodies for Cloud Storage upload, which I consider a non-starter: https://github.com/google-apis-rs/google-cloud-rs/issues/48

Use tonic-build directly from Rust.

If I’m not misunderstanding, you could both decode the gRPC protobuf AND write to delta lake in Rust. Tonic, Delta-rs.

Tonic

Just to double check Is this the correct repo?

Wasm isn't involved much actually. Basically, the frontend asks the backend to perform a gRPC call on its behalf using Tauri events. They are like named channels on which you can send any serde-compatible value. But the backend is a normal Rust program so there are no constraints there. I use prost-reflect to encode/decode Protobuf messages according to Protobuf descriptors loaded at runtime and make the actual requests using tonic from the tokio ecosystem. prost-reflect is necessary because, normally, tonic expects the Protobuf descriptor to be known at compile time so it can make some code generation behind the scenes.

You could have a look at gRPC i.e. https://github.com/hyperium/tonic

Looking at this example code: https://github.com/hyperium/tonic/blob/master/examples/src/tower/server.rs

The remaining gap is remote actors, since you still need some kind of serialization between them, and take your pick of standards for that one such as gRPC using Tonic.
