//! OPC-UA Pub/Sub **Part 14** (UADP) — native pure-Rust wire stack.
//!
//! Crate `zerodds-opcua-pubsub`. Safety classification: **STANDARD**.
//! Spec: OPC Foundation **Part 14 — PubSub** + **Part 6 — Mappings**
//! (binary encoding).
//!
//! # Scope and relationship to `zerodds-opcua-gateway`
//!
//! [`zerodds-opcua-gateway`](https://docs.rs/zerodds-opcua-gateway) is
//! the OMG **DDS-OPCUA 1.0** bridge — a pure type-system + AddressSpace
//! *mapping* library with no wire I/O. This crate adds the OPC Foundation
//! **Part 14** Pub/Sub *transport*: it serialises the gateway type model
//! (`NodeId`, `Variant`, `DataValue`, …) into the OPC-UA binary encoding
//! and frames it as UADP `NetworkMessage`s.
//!
//! The two specs are distinct families: DDS-OPCUA 1.0 bridges OPC-UA into
//! the DDS global data space; Part 14 is OPC-UA's own publish/subscribe
//! wire protocol. This crate is therefore an additive profile, not a
//! change to the gateway.
//!
//! # Layering (built incrementally)
//!
//! 1. [`binary`] — OPC-UA Part 6 binary encoding (the foundation; also
//!    usable by the Client/Server gateway).
//! 2. UADP `NetworkMessage` / `DataSetMessage` framing.
//! 3. PubSub configuration model + `DataSetWriter` / `DataSetReader`.
//! 4. UADP discovery (`DataSetMetaData`).
//! 5. PubSub security (`SecurityGroup` + Security Key Service).
//! 6. Transport carriers (UDP multicast, Ethernet, MQTT/AMQP).
//! 7. DataSet ↔ DDS-topic bridge + daemon.
