Struct CameraDevice 

pub struct CameraDevice {
    pub id: String,
    pub label: String,
    pub is_default: bool,
    pub gst_source: Option<String>,
}

One attached camera device with a stable ID, a human-readable label, and a flag indicating whether the OS treats it as the default.

id is derived from the device name via FNV-1a hashing so the same camera produces the same ID across reboots even when the OS’s underlying device-id string is non-stable (macOS AVFoundation has a history of doing this).

Fields

id: String

Stable identifier — used by M-CAM.4’s “last-used camera” persistence and by M-CAM.2’s start_preview(camera_id) IPC.

label: String

Human-readable label (e.g. "FaceTime HD Camera").

is_default: bool

true for the first device the OS lists. There’s no canonical “default camera” concept in the gst output, so we fall back to “first in the list” — which generally matches the macOS / Windows default-device selection.

gst_source: Option<String>

gst-launch source-element tokens that pin capture to this physical device — extracted from gst-device-monitor-1.0’s per-device hint line (e.g. "avfvideosrc device-index=0"). None when the parser couldn’t find a hint line; callers should fall back to autovideosrc in that case. Used by super::gstreamer_video::GstreamerVideoCapture::from_camera to actually route to the picked camera (M-CAM.4).

Trait Implementations

impl Clone for CameraDevice

fn clone(&self) -> CameraDevice

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CameraDevice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CameraDevice

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CameraDevice

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CameraDevice

fn eq(&self, other: &CameraDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CameraDevice

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CameraDevice
