ng-gateway-sdk 0.1.0

//! Unified supervision foundation for southward drivers and northward plugins.
//!
//! This module provides the shared building blocks for a high-performance gateway:
//! - A structured, cheap-to-clone connection state model (`ConnectionState`)
//! - A lock-free handle publication mechanism (`HandleCell`)
//! - Low-frequency model conversion contracts (`model_convert`)
//!
//! The main goal is to ensure **one authoritative lifecycle semantics** across all
//! connection-oriented components while keeping the data-plane hot path:
//! - lock-free
//! - allocation-free (besides cheap `Arc` clones)
//! - predictable under load
