viva-zenoh-api

Shared wire protocol types for GenICam camera services over Zenoh.

This crate defines the data contract between a camera service (viva-service) and its clients (e.g. genicam-studio). It has no Zenoh dependency -- it is a pure data contract built on serde.

Disclaimer -- Independent open-source Rust implementation of GenICam-related standards. Not affiliated with, endorsed by, or the reference implementation of EMVA GenICam. GenICam is a trademark of EMVA.

Features

• Discovery -- DeviceAnnounce, DeviceStatus
• Node values -- NodeValueUpdate, NodeSetRequest, NodeOpResponse, bulk read types
• Acquisition -- AcquisitionCommand, AcquisitionStatus
• Image framing -- PixelFormat, ImageMeta, FrameHeader (16-byte binary header)
• Key expressions -- helper functions for building Zenoh topic paths

Usage

[dependencies]
viva-zenoh-api = "0.1"

use viva_zenoh_api::{DeviceAnnounce, NodeValueUpdate, keys};

let key = keys::node_value("camera-01", "ExposureTime");
assert_eq!(key, "viva-genicam/devices/camera-01/nodes/ExposureTime/value");
