//!
//! Crate `zerodds-dlrl`. Safety classification: **STANDARD**.
//!
//! DLRL (Data Local Reconstruction Layer) is an optional DDS profile
//! that provides an object-centric cache on top of DCPS with identity
//! tracking, relationship resolution, and transactional updates
//! (Spec §2.1.3).
//!
//! # Modules
//!
//! * [`object_cache`] — object cache with identity tracking + WeakRef
//!   (Spec §B.2 + §B.6).
//! * [`transaction`] — transaction semantics with optimistic concurrency
//!   (Spec §B.7.4).
//! * [`relationship`] — relationship resolver (mono/bidirectional,
//!   compositional/referential, cascaded update/delete) (Spec §B.5).
//! * [`subscription`] — HomeFactory/HomeListener/ObjectListener
//!   (Spec §B.3 + §B.6).
//! * [`query`] — query engine with filter/order/limit (Spec §B.7).
//! * [`pragma`] — DLRL pragma parser (`#pragma DCPS_DATA_TYPE` etc.).
