Rust SDK for AG-UI

[NathanTarbert]

Develop a Rust SDK for the AG-UI Protocol

[wdoppenberg]

I'm willing to make a first draft, then we can see how to go forward from there.

[NathanTarbert]

Thank you @wdoppenberg, sounds good.

I will assign this to you, and anyone else wanting to join the effort can speak up as well.

Anything in particular that @wdoppenberg need help with here?

[wdoppenberg]

@NathanTarbert The types & client are nearly ready for testing. So far the following is done:

• Types
• Events
• Subscriber trait
• Event handling through EventHandler (this setup varies a bit from the source Typescript impl)
• Agent trait
• HttpAgent struct & implementation
• Functional examples using servers from https://ai.pydantic.dev/examples/ag-ui/

The following are on my TODO list:

• Agent "state" handling review (currently not part of any Agent's state due to mutability constraints)
• Run parameters DX improvements
• More elaborate error handling (especially for deserialization errors)
• Retries?
• Documentation
• JSON Patch types testing and upstreaming into ag-ui-core

If you want to give it a go already please use the given examples. They have an associated Python server app under scripts, which you can run using uv run <script.py>.

Hey @wdoppenberg, @kevinbayes & @attackordie are offering to help out where you need it. Can you let us know how it's going and if you'd like to take them up on it?

[wdoppenberg]

@NathanTarbert the only thing missing right now is the documentation. I'll get on this tomorrow.

Great, thanks so much for the update @wdoppenberg!
