Enum BlockingListenerRequest

pub enum BlockingListenerRequest {
    OnResumeStarted {
        responder: BlockingListenerOnResumeStartedResponder,
    },
    OnSuspendFailed {
        responder: BlockingListenerOnSuspendFailedResponder,
    },
    _UnknownMethod {
        ordinal: u64,
        control_handle: BlockingListenerControlHandle,
        method_type: MethodType,
    },
}

Interface implemented by components which elect to receive power-state callbacks from a Session, and have the Session block related power operations until the component replies.

Closing the server endpoint of BlockingListener will remove the blocking listener from the registry and unblock related power operations.

Variants

OnResumeStarted

Called by the ListenerRegistry to inform the component that the system has started resuming.

The callee SHOULD minimize the time it (the callee) takes to reply, since other power operations may block until the callee replies.

The caller SHOULD interpret an UNKNOWN_METHOD response as an indication that the callee has no work that would block the resume process.

Fields

responder: BlockingListenerOnResumeStartedResponder

OnSuspendFailed

Called by the ListenerRegistry to inform the component that a suspend attempt failed.

The callee SHOULD minimize the time it (callee) takes to reply, since later suspends may block until the callee replies.

The caller SHOULD interpret an UNKNOWN_METHOD response as an indication that the callee has no work that would block future power-state changes.

Fields

responder: BlockingListenerOnSuspendFailedResponder

_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: BlockingListenerControlHandle

method_type: MethodType
