Module SpineConnection 

Spine Connection Module ☀️ 🟡 MOUNTAIN_GROVE_WASM - WASM+Rhai extension host connection

This module provides gRPC-based communication for extension host integration. Maintains full backwards compatibility while adding optional EchoAction support.

Architecture (Backwards Compatible)

• Legacy RPC Layer: Original gRPC client (unchanged)
• New EchoAction Layer: Optional bidirectional actions (feature-gated)
• Dual Protocol: Both can be used simultaneously

Feature Gates

• grove_rpc (default) - Enable legacy RPC layer
• grove_echo (new, feature-gated) - Enable EchoAction layer

Usage

Legacy (Unchanged)

use crate::Protocol::{ProtocolConfig}; let mut connection = SpineConnection::new(config); connection.Connect().await?; let response = connection.SendRequest(request).await?;

With EchoAction (New, Optional)

let mut connection = SpineConnection::new(config); connection.Connect().await?; connection.ConnectEchoClient().await?;

// Use either method let response = connection.SendRequest(request).await?; // OLD: works let echo_response = connection.SendEchoAction(action).await?; // NEW: optional
