//! Protocol adapters for consistency engine
//!
//! Protocol adapters implement the ProtocolAdapter trait to integrate
//! individual protocols (HTTP, GraphQL, gRPC, etc.) with the consistency engine.
//!
//! Each adapter listens to state change events and updates its protocol-specific
//! state accordingly, ensuring all protocols reflect the unified state.

use crate::consistency::{PersonaProfile, StateChangeEvent};
use crate::protocol_abstraction::Protocol;
use crate::Result;

/// Trait for protocol adapters
///

/// They receive state change events and update their protocol-specific state
