Enum Capability 

#[repr(C)]
pub enum Capability {
    Camera = 0,
    Microphone = 1,
    ScreenCapture = 2,
    Geolocation = 3,
    GeolocationBackground = 4,

    Calendars = 10,
    Reminders = 11,
    Notifications = 12,

}

One closed enum covering every capability the framework can request.

The variant set deliberately omits fields like facing / accuracy / mode from the research brief — those parameters belong on the bearing NodeType (e.g. NodeType::CameraPreview(CameraSource::Front)) so they can change between layout passes without forcing a re-prompt. The Reconfigure diff event carries the new params when a node mutates.

Variants

Camera = 0

Camera access (front or back, declared per node).

Microphone = 1

Microphone access. iOS gates this separately from camera.

ScreenCapture = 2

Entire-screen or per-window capture.

Geolocation = 3

Geolocation (precise vs approximate is per-node, not per-capability).

GeolocationBackground = 4

Background geolocation. A separate iOS / Android permission gate.

Biometric = 5

FaceID / TouchID / Hello / BiometricPrompt.

Motion = 6

Motion sensor data (accelerometer + gyro + magnetometer).

PhotoLibrary = 7

PhotoKit / MediaStore read.

PhotoLibraryWrite = 8

PhotoKit add-only / MediaStore write.

Contacts = 9

Contacts list.

Calendars = 10

Calendar entries.

Reminders = 11

Reminders (iOS only — Android collapses into Calendars).

Notifications = 12

Push / local notification scheduling.

Bluetooth = 13

Bluetooth foreground.

BluetoothBackground = 14

Bluetooth background. Separate iOS Info.plist key + Android permission.

NearbyWifi = 15

Nearby Wi-Fi (Android 13+).

LocalNetwork = 16

Local network multicast (iOS 14+).

AppTrackingTransparency = 17

iOS App Tracking Transparency (IDFA consent, iOS 14.5+).

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl Hash for Capability

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 Ord for Capability

fn cmp(&self, other: &Capability) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Capability

fn eq(&self, other: &Capability) -> 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 PartialOrd for Capability

fn partial_cmp(&self, other: &Capability) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
