Implementations§

source§

impl DataProviderSynchronousProxy

source

pub fn new(channel: Channel) -> Self

source

pub fn into_channel(self) -> Channel

source

pub fn wait_for_event(&self, deadline: Time) -> Result<DataProviderEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

source

pub fn get_snapshot( &self, params: GetSnapshotParameters, ___deadline: Time ) -> Result<Snapshot, Error>

Returns a snapshot of the device’s state.

snapshot may be empty if there was an issue generating the snapshot.

source

pub fn get_screenshot( &self, encoding: ImageEncoding, ___deadline: Time ) -> Result<Option<Box<Screenshot>>, Error>

Returns an image of the current view encoded in the provided encoding.

screenshot may be null if the encoding is not supported, the device does not have a display, or there is not enough memory to allocate the screenshot image.

The screenshot is provided separately from the snapshot as callers might want to block on this call before changing the view while collecting a snapshot in the background is fine. There are also a lot of clients that are not interested in the screenshot.

source

pub fn get_annotations( &self, params: GetAnnotationsParameters, ___deadline: Time ) -> Result<Annotations, Error>

Returns a set of annotations about the device’s state.

annotations may be empty if there was an issue collecting them.

These are the same annotations as provided through GetSnapshot() - some clients only want the annotations while others want both the annotations and the snapshot and generating the snapshot can take significantly more time than collecting the annotations, e.g., logs are only part of the snapshot and not part of the annotations and can take some time.
