Struct GeolocationManager 

pub struct GeolocationManager {
    pub latest_fix: Option<LocationFix>,
    pub active_config: Option<GeolocationProbeConfig>,
    /* private fields */
}

Cross-platform geolocation state. One per App (the OS gives us a single per-process subscription, not per-window).

Fields

latest_fix: Option<LocationFix>

Most recent fix from the platform backend, or None until the first native sample arrives (or None again after a Release).

active_config: Option<GeolocationProbeConfig>

Active probe config — set on each Subscribe / Reconfigure, cleared on Release.

Implementations

impl GeolocationManager

pub fn new() -> Self

pub fn latest_fix(&self) -> Option<LocationFix>

pub fn refcount(&self) -> u32

pub fn set_latest_fix(&mut self, fix: LocationFix) -> bool

Platform backend writes the freshly-received fix. Returns true if the fix actually advanced (different from the previous one) so the caller can mark the window dirty for relayout.

Compared via bit-pattern equality so missing fields (encoded as f32::NAN) compare equal — PartialEq returns false on NaN-vs-NaN, which would make every fix look “changed” even when nothing actually moved.

pub fn take_pending_events(&mut self) -> Vec<GeolocationDiffEvent>

Drain queued diff events. Platform backend calls this once per frame.

pub fn diff_layout<F>(&mut self, for_each_probe: F)

where F: FnMut(&mut dyn FnMut(GeolocationProbeConfig)),

Diff entry point. The layout pass walks the styled DOM for GeolocationProbe nodes and feeds each (config, node_id) pair to the closure. The manager bumps the refcount, watches for config drift, and enqueues the right Subscribe / Release / Reconfigure event.

Trait Implementations

impl Clone for GeolocationManager

fn clone(&self) -> GeolocationManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeolocationManager

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

Formats the value using the given formatter.

impl Default for GeolocationManager

fn default() -> GeolocationManager

Returns the “default value” for a type.

impl PartialEq for GeolocationManager

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