Struct DeviceStateWatcherProxy 

pub struct DeviceStateWatcherProxy { /* private fields */ }

Implementations

impl DeviceStateWatcherProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.usb.policy/DeviceStateWatcher.

pub fn take_event_stream(&self) -> DeviceStateWatcherEventStream

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

Panics

Panics if the event stream was already taken.

pub fn watch_device_state( &self, ) -> QueryResponseFut<DeviceStateWatcherWatchDeviceStateResult, DefaultFuchsiaResourceDialect>

Notify a client of an updated device state value via a hanging get. The first time this is called, it will return right away with the current state. Subsequent calls will hang until there is a change to report. Returns a table containing the updated device state.
