Struct ControllerSynchronousProxy

pub struct ControllerSynchronousProxy { /* private fields */ }

Implementations

impl ControllerSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ControllerEvent, 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 notify( &self, view_ref: ViewRef, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Informs the implementer of Controller that further keyboard data should be routed to the keystroke/text consumer associated with view_ref.

Notes

• The callee should monitor the provided ViewRef for a ZX_EVENTPAIR_PEER_CLOSED signal (see documentation for fuchsia.ui.views.ViewRefControl).
• When the ViewRef receives ZX_EVENTPAIR_PEER_CLOSED, the callee should stop delivering keystroke/text to the consumer associated with view_ref.
• The caller should wait for each call to be acknowledged before calling again, to avoid queueing large numbers of of updates.
