kcan-viewer

Scrin pane-wall dashboard components for KCAN viewer apps.

kcan-viewer is a reusable viewer library for rendering actuator wall dashboards: pane per actuator, health labels, metrics, messages, and bus summary lines. It uses scrin = "0.1.83", scrin-widgets = "0.2.7", and the dependency-light kcan-core frame types.

The main user-facing command remains kcan. Use kcan-viewer when you want to embed KCAN dashboard panes inside a larger terminal app or build a standalone viewer binary.

use kcan_core::{CanFrame, CanId};
use kcan_viewer::{PaneWall, ViewerState};

let frame = CanFrame::new(CanId::extended(0x501)?, &[0x01, 0x02])?;
let state = ViewerState::from_frames("Bench", &[frame]);
let output = PaneWall::new().render_plain(&state, 80, 20);

assert!(output.contains("Bench"));
