Struct ElementControlProxy 

pub struct ElementControlProxy { /* private fields */ }

Implementations

impl ElementControlProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.power.broker/ElementControl.

pub fn take_event_stream(&self) -> ElementControlEventStream

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

Panics

Panics if the event stream was already taken.

pub fn open_status_channel( &self, status_channel: ServerEnd<StatusMarker>, ) -> Result<(), Error>

Register a new Status channel on which Power Broker will send read-only updates of the element’s current power level. This method is intended to allow element owners to give read-only access to the element’s current power level to clients by opening and transferring this channel.

pub fn register_dependency_token( &self, token: Event, ) -> QueryResponseFut<ElementControlRegisterDependencyTokenResult, DefaultFuchsiaResourceDialect>

Register a token which will permit the bearer to add either a dependency upon this element.

pub fn unregister_dependency_token( &self, token: Event, ) -> QueryResponseFut<ElementControlUnregisterDependencyTokenResult, DefaultFuchsiaResourceDialect>

Unregister a token previously registered via RegisterDependencyToken.

pub fn add_dependency( &self, dependent_level: u8, requires_token: Event, requires_level_by_preference: &[u8], ) -> QueryResponseFut<ElementControlAddDependencyResult, DefaultFuchsiaResourceDialect>

Add a new dependency to an existing element. If any open leases would incorporate this dependency, the required element and any transitively required elements must complete all necessary transitions (via ElementRunner.SetLevel calls) before this method will return.

fn as_channel(&self) -> &AsyncChannel

Get a reference to the proxy’s underlying channel.

fn into_client_end(self) -> Result<ClientEnd<Self::Protocol>, Self>

Attempt to convert the proxy back into a client end.

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, NullableHandle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
