Struct MouseSourceV2SynchronousProxy 

pub struct MouseSourceV2SynchronousProxy { /* private fields */ }

Implementations

impl MouseSourceV2SynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<MouseSourceV2Event, 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 acknowledge_events( &self, last_acknowledged_event_stamp: u64, ) -> Result<(), Error>

Acknowledges receipt of events up to last_acknowledged_event_stamp.

This grants the server “credits” to send more events. All events sent with a last_event_stamp less than or equal to last_acknowledged_event_stamp are considered acknowledged.

The server (Scenic) will throttle event delivery when unacknowledged events in flight reach MOUSE_SOURCE_V2_MAX_UNACKNOWLEDGED_EVENTS (or a product-configured maximum). Clients should send acknowledgments periodically (e.g. before reaching the limit, such as within 20 remaining credits) to avoid being throttled.

last_acknowledged_event_stamp must be strictly increasing. Non-compliance results in channel closure.
