Struct ViewRefInstalledProxy

pub struct ViewRefInstalledProxy { /* private fields */ }

Implementations

impl ViewRefInstalledProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.views/ViewRefInstalled.

pub fn take_event_stream(&self) -> ViewRefInstalledEventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch( &self, view_ref: ViewRef, ) -> QueryResponseFut<ViewRefInstalledWatchResult, DefaultFuchsiaResourceDialect>

Sets up a callback to fire when the requested |view_ref| is installed.

• If |view_ref| has not already been installed, the |Watch| response will fire when it is.
• If |view_ref| has already been installed, the |Watch| response will fire immediately.
• If |view_ref| is invalid, or becomes invalid (perhaps because the view was destroyed), the |Watch| call returns with an error. The error is not guaranteed to be immediate, but a ViewRef holder can itself determine ViewRef validity by listening for ZX_EVENTPAIR_PEER_CLOSED.

Flow control: The caller is allowed multiple |Watch| calls on multiple ViewRefs. There is at most one response per call back to the client.

Note: Prior to installation, this |Watch| call is kept alive as long as the ViewRef is valid.
