Crate zerodds_discovery 

Crate zerodds-discovery. Safety classification: SAFE.

DDSI-RTPS-Discovery für ZeroDDS — SPDP, SEDP, TypeLookup-Service.

Spec

• DDSI-RTPS 2.5 §8.5 — Simple Discovery Protocol (SPDP/SEDP).
• DDSI-RTPS 2.5 §8.5.3 — SPDP Builtin-Endpoints.
• DDSI-RTPS 2.5 §8.5.4 — SEDP Builtin-Endpoints.
• XTypes 1.3 §7.6.3.3.4 — TypeLookup-Service (TL_SVC_REQ_{WRITER,READER} + TL_SVC_REPLY_{WRITER,READER}).
• DDS-Security 1.2 §7.4.2 — Stateless + Volatile-Secure Builtin-Endpoints (sub-module security).

Public API

• spdp — SPDP Beacon-Sender + -Receiver + DiscoveredParticipantsCache mit last_seen-Lease-Tracking.
• sedp — SEDP Stack (Cache, Reader, Writer).
• type_lookup — TypeLookup-Service Server + Client + Builtin-Endpoint-GUIDs.
• security — DDS-Security Stateless + Volatile-Secure Builtin-Endpoint-Slots.
• capabilities::PeerCapabilities — DDSI-Capability-Bits.

Wiring an DCPS-Runtime

Die Discovery-Primitives sind wire-format-vollständig. Die Instantiierung der Builtin-Endpoint-Reliable-Writer/Reader-Pairs liegt im DCPS-Layer (crates/dcps/src/runtime.rs):

• SPDP: Best-Effort Writer + Reader auf ParticipantBuiltinTopicData.
• SEDP: Reliable Writer + Reader auf Publication-/Subscription-BuiltinTopicData.
• TypeLookup: Reliable Writer + Reader auf TypesRequest/ TypesReply-Topic mit Service-Instance-Name.
