Struct InputOwnershipProxy 

pub struct InputOwnershipProxy { /* private fields */ }

Implementations

impl InputOwnershipProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.input.internal/InputOwnership.

pub fn take_event_stream(&self) -> InputOwnershipEventStream

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

Panics

Panics if the event stream was already taken.

pub fn get_event( &self, target: InputOwnershipTarget, ) -> QueryResponseFut<InputOwnershipGetEventResult, DefaultFuchsiaResourceDialect>

Gets a duplicate handle to the shared kernel ownership_event whose orthogonal signals inform clients and the system pipeline when direct driver input access (fuchsia.input.report.Service) is granted or revoked:

• Virtcon (target = virtcon: {}): owns input iff InputOwnershipSignal.DISPLAY_UNOWNED is asserted.
• Starnix (target = view_ref): owns direct input iff both InputOwnershipSignal.DISPLAY_PLATFORM_OWNED and InputOwnershipSignal.INPUT_CLIENT_OWNED are asserted.
• SceneManager (target = platform: {}): owns platform pipeline input iff both InputOwnershipSignal.DISPLAY_PLATFORM_OWNED and InputOwnershipSignal.INPUT_PLATFORM_OWNED are asserted (pauses whenever DISPLAY_UNOWNED or INPUT_CLIENT_OWNED is asserted).

If target is set to an unsupported or unknown variant, the call returns InputOwnershipError.INVALID_TARGET.
