Crate zerodds_dlrl 

DDS Data-Local-Reconstruction-Layer (DLRL) — DDS 1.4 §2.2 + §B.

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.).
