Implementations§

Source§

impl UsageWatcherProxy

Source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.media/UsageWatcher.

Source

pub fn take_event_stream(&self) -> UsageWatcherEventStream

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

§Panics

Panics if the event stream was already taken.

Source

pub fn on_state_changed( &self, usage: &Usage, state: &UsageState, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Called on first connection and whenever the watched usage changes. The provided usage will always be the bound usage; it is provided so that an implementation of this protocol may be bound to more than one usage.

Clients must respond to acknowledge the event. Clients that do not acknowledge their events will eventually be disconnected.
