Struct Camera 

pub struct Camera {
    pub name: String,
    pub unique_id: String,
    pub serial_number: Option<String>,
    pub vendor_id: u16,
    pub product_id: u16,
    pub max_resolution: Option<(u32, u32)>,
    pub max_fps: Option<u32>,
}

A connected USB Video Class camera.

Fields

name: String

Human-readable name, e.g. "Logitech StreamCam".

unique_id: String

OS capture-layer identifier (AVFoundation uniqueID, DirectShow device path). Used to open preview/controls; may embed a USB location and so change when the camera is moved to another port.

serial_number: Option<String>

USB iSerialNumber when the device reports one. Port-stable; preferred for persisted config keys via Self::config_key.

vendor_id: u16

USB vendor id (0x046d for Logitech).

product_id: u16

USB product id (e.g. 0x0893 for the StreamCam).

max_resolution: Option<(u32, u32)>

Largest supported frame size (width, height), when the OS reports the device’s formats. Read from metadata only — no capture, no permission.

max_fps: Option<u32>

Highest supported frame rate (fps) across all formats, when known.

Implementations

impl Camera

pub fn config_key(&self) -> String

Persistence key that is stable across USB ports.

Prefers the USB serial when the device reports one. When it doesn’t, falls back to a model-scoped key (camera:vid:pid) so settings survive a port change. Two serial-less units of the same model share this key (no stronger USB identity); the GUI keeps them as separate live cards via the OS capture id, not via this settings key.

Trait Implementations
