Support for Rust client

[banool]

Hey hey, I'm wondering if there is a recommended way to call an RSPC API from Rust? As far as I can tell there is no way to generate a client automatically. I saw some issues about OpenAPI but it doesn't seem to be released yet. I don't think using something like utoipa would work, there is no way to derive the necessary traits.

I suppose the best thing we could manage is to put the Rust types for the requests and responses (which derived specta::Type) into their own crate and then write our own client based on those. Or idk, something insane where we run compile the client into JS and then run it via Deno or something 😅

Any ideas would be appreciated!

Sorry, completely missed this issue.

Right now we don't have an offcial way but I have started work on a prototype client for Rust previewed here (Note it's part of #326). I would be very open to contributions on it if you wanted to take it for a spin but be aware it's more a proof of concept at the moment as I wanted to iron out how the type exporter would work before we stablise the new API.

OpenAPI support is definitely a bit furthur away as it's much harder to integrate with.

(going to keep this issue open until it's stable so we have a place to track it's progress)

• How are content types and binario going to work?

Awesome, I'll check out the prototype. The time has finally come, I need to hit an rspc server from another Rust service, so I'll let you know how I go with it.

One question, I see that router v2 has been merged to main (#326) but the TS client hasn't (#332). Does this mean we shouldn't use main at the moment? It seems like this Rust client is based on router v2, so it wouldn't be usable with an old rpsc server? We're currently using this commit: 56d0230.
