Struct SensorManager 

pub struct SensorManager {
    pub accelerometer: Option<SensorReading>,
    pub gyroscope: Option<SensorReading>,
    pub magnetometer: Option<SensorReading>,
    pub pending_event: bool,
    pub has_listeners: bool,
}

Cross-platform sensor state. One per App — the OS exposes a single per-process sensor subscription, not per-window.

Fields

accelerometer: Option<SensorReading>

Latest accelerometer reading (m/s²), or None until a sample arrives.

gyroscope: Option<SensorReading>

Latest gyroscope reading (rad/s).

magnetometer: Option<SensorReading>

Latest magnetometer reading (µT).

pending_event: bool

true when a reading advanced since the last event-pass drain. Set by set_reading, read by the EventProvider impl, cleared by clear_pending_event.

has_listeners: bool

true while any node in the current layout registers a SensorChanged callback (Hover or Window filter). Recomputed on every relayout by the DOM walk in shell2::common::layout; the capability pump polls the platform sensor backend only while this is set (MWA-A1 arming signal — no listeners, no polling, no timer).

Implementations

impl SensorManager

pub fn new() -> Self

pub const fn reading(&self, kind: SensorKind) -> Option<SensorReading>

Latest reading for kind, or None if no backend has delivered one.

pub fn set_reading(&mut self, reading: SensorReading) -> bool

Apply a reading the backend delivered. Returns true if it advanced (bit-pattern different from the previous, so missing-as-NaN axes don’t make every sample look “changed”).

pub const fn clear_pending_event(&mut self)

Clear the pending-event flag. The dll calls this after the event pass has collected the SensorChanged event (mirrors clear_changeset).

pub const fn set_has_listeners(&mut self, has: bool)

Relayout walk reports whether any node listens for SensorChanged.

pub const fn has_listeners(&self) -> bool

true while the capability pump should poll the sensor backend.

Trait Implementations

impl Clone for SensorManager

fn clone(&self) -> SensorManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SensorManager

impl Debug for SensorManager

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

Formats the value using the given formatter.

impl Default for SensorManager

fn default() -> SensorManager

Returns the “default value” for a type.

impl EventProvider for SensorManager

fn get_pending_events(&self, timestamp: Instant) -> Vec<SyntheticEvent>

Yield a window-level SensorChanged event when a reading advanced since the last drain (target = root; read the value via CallbackInfo::get_sensor_reading inside the callback).

impl PartialEq for SensorManager

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

Equality operator ==.

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

Inequality operator !=.
