Struct PositionWatch 

pub struct PositionWatch {
    id: GeolocationWatchId,
    result_sender: GenericCallback<GeolocationResult>,
    options: GeolocationRequestOptions,
}

An ongoing subscription to position updates, corresponding to one call to navigator.geolocation.watchPosition()

Fields

id: GeolocationWatchId

result_sender: GenericCallback<GeolocationResult>

options: GeolocationRequestOptions

Implementations

impl PositionWatch

pub(crate) fn new( id: GeolocationWatchId, result_sender: GenericCallback<GeolocationResult>, options: GeolocationRequestOptions, ) -> Self

pub fn id(&self) -> GeolocationWatchId

The identifier used to stop this watch.

pub fn options(&self) -> &GeolocationRequestOptions

Hints about how positions should be acquired.

pub fn update(&self, position: GeolocationPositionData)

Deliver a new position to script. May be called any number of times.

pub fn error(&self, error: GeolocationError)

Report that a position could not be acquired. This does not end the watch: script keeps listening, and the embedder may still call PositionWatch::update() later.
