Struct MouseSourceV2Proxy 

pub struct MouseSourceV2Proxy { /* private fields */ }

Implementations

impl MouseSourceV2Proxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.pointer/MouseSourceV2.

pub fn take_event_stream(&self) -> MouseSourceV2EventStream

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

Panics

Panics if the event stream was already taken.

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.
