Struct FocusChainProviderProxy

pub struct FocusChainProviderProxy { /* private fields */ }

Implementations

impl FocusChainProviderProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.focus/FocusChainProvider.

pub fn take_event_stream(&self) -> FocusChainProviderEventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch_focus_koid_chain( &self, payload: &FocusChainProviderWatchFocusKoidChainRequest, ) -> QueryResponseFut<FocusKoidChain, DefaultFuchsiaResourceDialect>

Subscribe to changes in the focus chain (koids only) with a hanging-get pattern.

The server responds immediately with the initial state, and afterwards whenever a change occurs. Updates are not queued up for slow clients; only the latest state is sent.

It is invalid to call this method while a previous call is pending. Doing so will cause the server end of the protocol to be closed.
