Struct PositionRequest 

struct PositionRequest {
    success_callback: TracedCallback<PositionCallback<DomTypeHolder>>,
    error_callback: Option<TracedCallback<PositionErrorCallback<DomTypeHolder>>>,
    options: RequestOptions,
    watch_id: Option<u32>,
    timeout_handle: Cell<Option<OneshotTimerHandle>>,
    settled: Cell<bool>,
    watching: Cell<bool>,
    terminated: Cell<bool>,
}

The state of a single in-flight call to getCurrentPosition() or watchPosition().

Fields

success_callback: TracedCallback<PositionCallback<DomTypeHolder>>

error_callback: Option<TracedCallback<PositionErrorCallback<DomTypeHolder>>>

options: RequestOptions

watch_id: Option<u32>

The watchId returned by watchPosition(), or None for getCurrentPosition().

timeout_handle: Cell<Option<OneshotTimerHandle>>

The timeout armed for the acquisition currently under way, if any.

settled: Cell<bool>

Set once the current acquisition has produced a result, so that a reply racing the timeout is ignored.

watching: Cell<bool>

Whether the embedder has been asked to keep this watch updated.

terminated: Cell<bool>

Set when the request has failed for good, so that a watch is forgotten once its error callback has run rather than waiting for updates that will never come.
