Module a2a 

A2A Protocol Implementation

First-class support for the Agent-to-Agent (A2A) protocol, enabling this agent to work as both a client and server in the A2A ecosystem.

Transports

• JSON-RPC (default) — server.rs / client.rs
• gRPC — grpc.rs (tonic-based, compiled from proto/a2a/v1/a2a.proto)

Re-exports

pub use client::A2AClient;
