    },
}

A service for exposing events and power elements managed by the system activity governor (SAG).

SAG is responsible for managing the execution state of the hardware platform. The hardware platform consists of the components required to execute code on the device. This typically includes the CPU, memory, operating system, and other components required for these components to function (clock trees, power domains, etc.).

Variants

GetPowerElements

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.

Fields

responder: ActivityGovernorGetPowerElementsResponder

TakeWakeLease

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.

Fields

name: String

responder: ActivityGovernorTakeWakeLeaseResponder

AcquireWakeLease

Creates a lease that blocks suspension of the hardware platform.

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

Fields

name: String

responder: ActivityGovernorAcquireWakeLeaseResponder

TakeApplicationActivityLease

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.

Fields

name: String

responder: ActivityGovernorTakeApplicationActivityLeaseResponder

RegisterListener

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.

Fields

payload: ActivityGovernorRegisterListenerRequest

responder: ActivityGovernorRegisterListenerResponder

_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: ActivityGovernorControlHandle

method_type: MethodType
