Struct fidl_fuchsia_feedback::DataProviderProxy

pub struct DataProviderProxy { /* private fields */ }

Implementations

impl DataProviderProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.feedback/DataProvider.

pub fn take_event_stream(&self) -> DataProviderEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn get_snapshot( &self, params: GetSnapshotParameters ) -> QueryResponseFut<Snapshot>

Returns a snapshot of the device’s state.

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

pub fn get_screenshot( &self, encoding: ImageEncoding ) -> QueryResponseFut<Option<Box<Screenshot>>>

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.

pub fn get_annotations( &self, params: &GetAnnotationsParameters ) -> QueryResponseFut<Annotations>

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.
