Enum ListenerRegistryRequest

pub enum ListenerRegistryRequest {
    RegisterBlockingListener {
        listener: ClientEnd<BlockingListenerMarker>,
        responder: ListenerRegistryRegisterBlockingListenerResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: ListenerRegistryControlHandle,
        method_type: MethodType,
    },
}

Allows components to request callbacks on power-state changes.

The timing of acknowledgements from BlockingListeners affects the suspend and resume processes, as the ListenerRegistry MUST wait for the BlockingListeners to respond.

Note, however, that the ListenerRegistry MAY apply a timeout to the responses.

Variants

RegisterBlockingListener

Registers listener with the registry.

When the ListenerRegistry learns of power state changes, the ListenerRegistry will forward the event to the listener.

See documentation of the BlockingListener methods for details on which events are available, and the semantics of each callback.

The ListenerRegistry MUST continue to forward events to the listener, even after the ListenerRegistry connection is closed.

Replaces any existing listener that was previously registered.

Fields

listener: ClientEnd<BlockingListenerMarker>

responder: ListenerRegistryRegisterBlockingListenerResponder

_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: ListenerRegistryControlHandle

method_type: MethodType
