zenoh-plugin-grpc

Rust gRPC plugin, bridge, and SDKs for Zenoh 1.7.2 and rust 1.85.0 now.

This plugin starts a gRPC server inside zenohd and exposes Zenoh operations over gRPC so that external applications (python/c++) can interact with Zenoh via gRPC calls.

This is useful for one zenoh peer/router acting as a communication bridge and multiple external (local) applications connecting to it to send and receive messages.

Workspace

• zenoh-plugin-grpc: plugin loaded by zenohd
• zenoh-bridge-grpc: standalone executable with the plugin linked in
• zenoh-grpc-proto: gRPC proto and generated Rust types, used by gRPC server (zenoh-plugin-grpc) and clients (zenoh-grpc-client-rs).
• zenoh-grpc-client-sdk/zenoh-grpc-client-rs: Rust client core
• zenoh-grpc-client-sdk/zenoh-grpc-python: Python bindings
• zenoh-grpc-client-sdk/zenoh-grpc-c: C wrapper
• zenoh-grpc-client-sdk/zenoh-grpc-cpp: C++ wrapper

Build

cargo check --workspace
cargo build --release

Quick Start

Start the standalone bridge:

cargo run -p zenoh-bridge-grpc

Then connect from a client SDK to:

unix:///tmp/zenoh-grpc.sock
