ZeroDDS Documentation

ZeroDDS is a pure-Rust implementation of OMG DDS 1.4 + DDSI-RTPS 2.5 + DDS-Security 1.2 + DDS-XTypes 1.3, with bindings for C, C++, C#, Java, Python, TypeScript, and a ROS-2 RMW plugin.

For the per-crate API reference see docs.rs; for the full website see https://zerodds.org.

Getting started

• Overview · Concepts · Installation · First publisher / subscriber

Architecture

• Component / crate map — how the ~120 crates group into layers, and the dependency direction.
• Data flow on write — the hot path when application code publishes a sample.

Configuration

• Overview · Runtime config · QoS policies · Transport · Security · Observability

IDL & wire types

• IDL reference — OMG-IDL 4.2 as ZeroDDS' wire-type language, compiled by zerodds-idlc.
• zerodds-idlc handbook — the end-user compiler manual: CLI, annotations, build integration, cookbook.
• CDR wire format — the XCDR1 / XCDR2 byte form of every IDL construct.

Integration per language

• Java — the pure-Java org.omg.dds.* PSM.
• TypeScript / WASM — the browser XCDR codec + WebSocket-bridge pattern.

Operations

• Overview · Deployment · Monitoring · Troubleshooting

Migration from another DDS

• Overview — from Cyclone DDS, Fast DDS, OpenDDS, or RTI Connext.

Where else to look

• Per-crate API reference — published on docs.rs; each crate also ships a README.md quick-start under crates/<name>/.
