3//!
4//! Agent-to-Agent (A2A) protocol implementation with JSON-RPC, REST, and gRPC bindings.
5//!
6//! ## Features
7//!
8//! - `client` — HTTP client for JSON-RPC and REST (reqwest)
9//! - `server` — HTTP server for JSON-RPC and REST (hyper)
10//! - `native` — Both client and server (default)
11//! - `grpc` — gRPC types (prost + tonic)
12//! - `grpc-client` — gRPC client transport
13//! - `grpc-server` — gRPC server service
14//! - `full` — Everything
