Crate turul_a2a_types 

Ergonomic Rust types for the A2A Protocol v1.0.

This crate wraps the prost-generated proto types from turul_a2a_proto with idiomatic Rust APIs, state machine enforcement on TaskState, and builder helpers on Task, Message, and Artifact.

All public types are #[non_exhaustive] — additive changes will not break downstream code.

Primary entry points

• Task, TaskStatus, TaskState — the core task object and its lifecycle
• Message, Part, Role — conversational payloads
• Artifact — outputs produced during task execution
• wire — JSON-RPC method constants and SSE event shapes

Raw proto access is available via proto for advanced use.
