Struct ActivityGovernorListenerProxy

pub struct ActivityGovernorListenerProxy { /* private fields */ }

Implementations

impl ActivityGovernorListenerProxy

pub fn new(channel: AsyncChannel) -> Self

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

pub fn take_event_stream(&self) -> ActivityGovernorListenerEventStream

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

Panics

Panics if the event stream was already taken.

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

Called when the activity governor detects a system resume.

This is only called when the wakeup reason returned by the platform requires a full system resume. The server is expected to respond once it has performed the operations required to keep the system awake, if needed.

SAG does not block on the response to this method, so the listener may safely call ActivityGovernor.AcquireWakeLease or ActivityGovernor.TakeApplicationActivityLease. In particular, it is not affected by https://fxbug.dev/389163722.

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

Called before the activity governor initiates a system suspension.

The server is expected to respond once it has performed the operations it needs to prepare itself for suspend, if any.

It is not safe for this method to call ActivityGovernor.AcquireWakeLease or ActivityGovernor.TakeApplicationActivityLease, or to perform any other action that blocks on raising Execution State above its Inactive level. Doing so will currently result in a deadlock. This constraint will be removed; see https://fxbug.dev/389163722.

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

Called when the activity governor detects a suspend failure.

The server is expected to respond to this notification. The activity governor will not attempt to suspend again until it receives the respond.

SAG does not block on the response to this method, so the listener may safely call ActivityGovernor.AcquireWakeLease or ActivityGovernor.TakeApplicationActivityLease. In particular, it is not affected by https://fxbug.dev/389163722.
