Enum Source 

#[non_exhaustive]
pub enum Source {
    Camera(Option<String>),
    Display(Option<String>),
    Window(String),
    App(String),
}

What to capture. Each variant carries the identifier that selects it, so a window can’t be captured without saying which one, and a camera id can’t reach the display backend.

The identifiers come from cameras, displays, windows, and apps; each listed item’s source() builds the matching variant.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Camera(Option<String>)

A camera / webcam. None opens the default camera.

The identifiers from cameras are an AVFoundation uniqueID on macOS, a /dev/videoN path on Linux, and a Media Foundation symbolic link on Windows. Bare numeric indices remain accepted on Linux and Windows.

Display(Option<String>)

A whole display. None opens the main display.

The id is a bare display index. macOS and Windows honor it; on Linux the xdg-desktop-portal picker owns selection and the id is ignored.

Window(String)

A single window, by the id windows reports. macOS only.

App(String)

Every window belonging to one application, by the id apps reports (a bundle identifier). Windows that open later are included. macOS only.
