Struct InputOwnershipSynchronousProxy

pub struct InputOwnershipSynchronousProxy { /* private fields */ }

Implementations§

impl InputOwnershipSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<InputOwnershipEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn get_event( &self, target: InputOwnershipTarget, ___deadline: MonotonicInstant, ) -> Result<InputOwnershipGetEventResult, Error>

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.
