langgraph4rust v0.2.0 – a stateful workflow engine for Rust, inspired by
Python's LangGraph.
You describe a workflow as a graph of typed-state nodes; the engine handles
parallel execution, conditional routing, and — new in 0.2.0 — a push-based
streaming API that emits real-time execution events.

It's early-stage and Apache-2.0 licensed. I'd genuinely appreciate feedback
on the API design — especially from anyone who's used LangGraph in Python.
What would you consider essential that's missing here?
