What it does: Robotheca's summary
- Provides publish/subscribe, store/query and compute in one stack with low overhead.
- The zenoh crate is the reference Rust implementation; other language bindings wrap it, except the pure-C zenoh-pico.
- The zenoh-ext crate adds AdvancedPublisher and AdvancedSubscriber for stronger delivery guarantees, plus lightweight serialization.
- The zenohd router is a standalone daemon that supports network infrastructure and can load plugins.
- Language bindings are listed for C, C++, Python, Kotlin, Java, TypeScript and Go.
