1//! WiFi-DensePose WebAssembly bindings
2//!
3//! This crate provides WebAssembly bindings for browser-based applications using
4//! WiFi-DensePose technology. It includes:
5//!
6//! - **mat**: WiFi-Mat disaster response dashboard module for browser integration
7//!
8//! # Features
9//!
10//! - `mat` - Enable WiFi-Mat disaster detection WASM bindings
11//! - `console_error_panic_hook` - Better panic messages in browser console
12//!
13//! # Building for WASM
14//!
15//! ```bash
16//! # Build with wasm-pack
17//! wasm-pack build --target web --features mat
18//!
19//! # Or with cargo
20//! cargo build --target wasm32-unknown-unknown --features mat
21//! ```
22//!
23//! # Example Usage (JavaScript)
24//!
25//! ```javascript
26//! import init, { MatDashboard, initLogging } from './wifi_densepose_wasm.js';
27//!
28//! async function main() {
29//!     await init();
30//!     initLogging('info');
31//!
32//!     const dashboard = new MatDashboard();
33//!
34//!     // Create a disaster event
35//!     const eventId = dashboard.createEvent('earthquake', 37.7749, -122.4194, 'Bay Area Earthquake');
36//!
37//!     // Add scan zones
38//!     dashboard.addRectangleZone('Building A', 50, 50, 200, 150);
39//!     dashboard.addCircleZone('Search Area B', 400, 200, 80);
40//!
41//!     // Subscribe to events
42//!     dashboard.onSurvivorDetected((survivor) => {
43//!         console.log('Survivor detected:', survivor);
44//!         updateUI(survivor);
45//!     });
46//!
47//!     dashboard.onAlertGenerated((alert) => {
48//!         showNotification(alert);
49//!     });
50//!
51//!     // Render to canvas
52//!     const canvas = document.getElementById('map');
53//!     const ctx = canvas.getContext('2d');
54//!
55//!     function render() {
56//!         ctx.clearRect(0, 0, canvas.width, canvas.height);
57//!         dashboard.renderZones(ctx);
58//!         dashboard.renderSurvivors(ctx);
59//!         requestAnimationFrame(render);
60//!     }
61//!     render();
62//! }
63//!
64//! main();
