Wire protocol types for reovim client-server communication.

This crate defines the message types and shared data structures used for communication between the reovim server and its clients (TUI, CLI, GUI).

Architecture

The protocol crate is designed to be:

• Minimal: Only serde dependencies (+ tonic/prost with grpc feature)
• Versioned: Types are organized under version modules (v1, v2, etc.)
• Shared: Used by both server and client crates

Protocol Versions

• v1: JSON-RPC 2.0 with cell-grid based rendering (default)
• v2: gRPC with raw-data model (requires grpc feature)

Example (v1 JSON-RPC)

use reovim_protocol::{RpcRequest, methods};

// Create a typed request
let request = RpcRequest::new(1, methods::STATE_CURSOR, serde_json::json!({}));

Example (v2 gRPC)

// Requires `grpc` feature
use reovim_protocol::v2::buffer_service_client::BufferServiceClient;

let mut client = BufferServiceClient::connect("http://127.0.0.1:12523").await?;
let response = client.get_raw_content(GetRawContentRequest::default()).await?;
