Struct CapabilityEntry 

pub struct CapabilityEntry {
    pub state: PermissionState,
    pub refcount: u32,
    pub last_subscriber: Option<DomNodeId>,
}

Per-capability state held across frames.

refcount is the number of distinct DOM nodes currently in the layout that subscribed to this capability. last_subscriber is the node that caused the most recent 0 → 1 transition; the platform backend uses it to anchor permission-related events back to a node (so an On::CameraPermissionDenied callback fires on the right CameraPreview).

Fields

state: PermissionState

refcount: u32

last_subscriber: Option<DomNodeId>

Trait Implementations

impl Clone for CapabilityEntry

fn clone(&self) -> CapabilityEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilityEntry

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

Formats the value using the given formatter.

impl PartialEq for CapabilityEntry

fn eq(&self, other: &CapabilityEntry) -> 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.
