rk_zenoh 0.2.2

Dart bindings for Zenoh over a narrow C ABI - publish, subscribe and liveliness for offline-first fleets, with an explicit answer to the stale Zenoh ID after a restart.

0.2.2

• macOS and iOS actually build now. The pod script phase shipped with CRLF line endings and exited 0 without invoking cargo, both Apple platforms need Security and CoreFoundation which the podspecs did not name, and the Dart loader asked for a dylib that is never produced. All fixed and verified on a Mac.

0.2.1

• Documentation is now in English throughout: README, CHANGELOG, CONTRIBUTING, SECURITY, doc/ and the example. The example in example/example.md was also stale — it called rkZenohVersion and hasNativeSession, which have not existed since 0.1.0 — and now shows the real API.

0.2.0

• The package became a Flutter FFI plugin: flutter build now invokes cargo itself and puts the library into the application on Windows, Linux and Android. Before this there was no flutter.plugin.platforms block in the pubspec, and the native side reached no build at all. macOS and iOS are written but have never been built.

0.1.0

First working version. 0.0.1 held the name and did nothing; nothing of it survives, including rkZenohVersion and hasNativeSession — those are gone.

• The rust/ crate: a C ABI over a stable subset of Zenoh 1.9.0. The unstable feature is not enabled, so Advanced Pub/Sub — publisher cache, history for late subscribers, gap detection and recovery — is absent, as are liveliness history and per-message reliability. What that means in practice is written up in doc/stable-subset.md.
• ZenohSession: open, put, delete, subscribe, liveliness tokens, and the list of reachable nodes. Every native call happens on a worker isolate the package creates itself; nothing runs on the caller's isolate.
• ZenohIdentity forces a decision about whether the Zenoh ID survives a restart. A pinned ID is rejected without TLS: it was measured that whoever claims it first keeps it — so a machine that knows a till's name cuts that till out of the fabric by booting earlier. The numbers and both ways out are in doc/stale-zid.md.
• Failure comes back as a returned value; panics are caught at the boundary. The kind of failure crosses the boundary by name (RkzErrorKind), as do modes, priorities, congestion control and sample kind.
• Freeing is deterministic and one-way: whoever received a handle frees it. The table is in doc/architecture.md.

The package deliberately ships no per-platform build scaffolding: cd rust && cargo build --release, and the library is located by an explicit path, by RK_ZENOH_LIBRARY, or next to the executable.

0.0.1

• Name claimed. No content yet: the package exercises the publishing pipeline rather than solving the problem.
