Enum ActivityGovernorListenerRequest

pub enum ActivityGovernorListenerRequest {
    OnResume {
        responder: ActivityGovernorListenerOnResumeResponder,
    },
    OnSuspendStarted {
        responder: ActivityGovernorListenerOnSuspendStartedResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: ActivityGovernorListenerControlHandle,
        method_type: MethodType,
    },
}

A listener for activity governor events.

Variants

OnResume

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. All dependencies of ExecutionStateLevel::SUSPENDING are guaranteed to be satisified when this call is issued, and the listener’s OnSuspendStarted method will be invoked before that guarantee is removed.

SAG does not block on the response to this method, so the listener may safely take actions that block on raising Execution State’s power level. In particular, it is not affected by https://fxbug.dev/391429689.

Fields

responder: ActivityGovernorListenerOnResumeResponder

OnSuspendStarted

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. All dependencies of ExecutionStateLevel::SUSPENDING are guaranteed to be satisified for the duration of this call.

It is not safe for this method to call ActivityGovernor.TakeApplicationActivityLease or to perform any other action that blocks on raising Execution State above its Inactive level. (However, AcquireWakeLease does not block in this way and is safe to call.) Doing so will currently result in a deadlock. This constraint will eventually be removed; see https://fxbug.dev/391429689.

Fields

responder: ActivityGovernorListenerOnSuspendStartedResponder

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ActivityGovernorListenerControlHandle

method_type: MethodType
