Struct MagnificationHandlerProxy

pub struct MagnificationHandlerProxy { /* private fields */ }

Implementations

impl MagnificationHandlerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.accessibility/MagnificationHandler.

pub fn take_event_stream(&self) -> MagnificationHandlerEventStream

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

Panics

Panics if the event stream was already taken.

pub fn set_clip_space_transform( &self, x: f32, y: f32, scale: f32, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Sets clip-space x-offset, y-offset, and scale for the presentation. x and y are in Vulkan NDC and are applied after scaling, which occurs about the center of the presentation. The callback indicates when the update has been presented. The identity transform (0, 0, 1) is the natural state.
