Struct ActivityGovernorProxy

pub struct ActivityGovernorProxy { /* private fields */ }

Implementations

impl ActivityGovernorProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.power.system/ActivityGovernor.

pub fn take_event_stream(&self) -> ActivityGovernorEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_power_elements( &self, ) -> QueryResponseFut<PowerElements, DefaultFuchsiaResourceDialect>

Gets the power elements owned by the activity governor.

If an error occurs while the server is registering a power element with the power broker or an error occurs while creating a token for a power element, then the channel to ActivityGovernor will be closed by the server and no response will be returned.

pub fn take_wake_lease( &self, name: &str, ) -> QueryResponseFut<EventPair, DefaultFuchsiaResourceDialect>

Creates a lease that blocks suspension of the hardware platform.

The hardware platform will not suspend as long as a valid LeaseToken exists.

If an error occurs while creating a token for the wake lease, then the channel to ActivityGovernor will be closed by the server and no response will be returned.

pub fn take_application_activity_lease( &self, name: &str, ) -> QueryResponseFut<EventPair, DefaultFuchsiaResourceDialect>

Creates a lease that blocks the system from dropping below the Application Activity ‘Active’ state. In particular, this blocks suspension of the hardware platform.

If an error occurs while creating a token for the activity lease, then the channel to ActivityGovernor will be closed by the server and no response will be returned.

pub fn register_listener( &self, payload: ActivityGovernorRegisterListenerRequest, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Registers a listener for activity governor events.

If there is an error in registering the listener, then the given ActivityGovernorListener channel will be closed before the response is sent.

To unregister, close the ActivityGovernorListener channel.

fn into_channel(self) -> Result<AsyncChannel, Self>

Attempt to convert the proxy back into a channel.

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<'_, Handle>>

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