Struct Config 

#[non_exhaustive]
pub struct Config {
    pub device: Option<String>,
    pub width: Option<u32>,
    pub height: Option<u32>,
    pub framerate: Option<u32>,
}

Webcam capture configuration. All fields are hints; the backend picks the closest supported mode.

#[non_exhaustive]: construct via Config::default and set fields, so new options can be added without breaking callers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

device: Option<String>

Platform device identifier. None opens the default camera.

• macOS (avfoundation): device index ("0") or name ("FaceTime HD Camera").
• Linux (v4l2): a /dev/videoN path.
• Windows (dshow): the device name (without the video= prefix).

width: Option<u32>

height: Option<u32>

framerate: Option<u32>
