Module camera 

Live camera capture: an in-app viewfinder frame source.

Unlike the one-shot image_picker (which presents the system camera UI), this exposes a running capture session whose latest frame the app polls to render its own viewfinder and run per-frame detection — matching the Android/desktop live-preview experience.

The platform backend installs an implementation via set_platform_camera (iOS AVCaptureSession, desktop nokhwa, …). No default: camera returns None where live capture is unsupported, so the app can fall back to the image picker.

Structs

CameraFrame

A single captured frame as tightly-packed RGBA8 (width * height * 4 bytes, row-major, no padding).

Enums

CameraError

Traits

Camera

A running (or startable) live camera. Implementations are Send + Sync so a background preview pump can start/stop and poll frames off the UI thread.

Functions

camera

The registered live camera, or None where live capture is unsupported.

clear_platform_camera

Removes any registered platform camera (tests/teardown).

set_platform_camera
