Struct ScenicSynchronousProxy

pub struct ScenicSynchronousProxy { /* private fields */ }

Implementations

impl ScenicSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<ScenicEvent, 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 create_session( &self, session: ServerEnd<SessionMarker>, listener: Option<ClientEnd<SessionListenerMarker>>, ) -> Result<(), Error>

Create a new Session, which is the primary way to interact with Scenic.

pub fn create_session2( &self, session: ServerEnd<SessionMarker>, listener: Option<ClientEnd<SessionListenerMarker>>, view_focuser: Option<ServerEnd<FocuserMarker>>, ) -> Result<(), Error>

Create a new Session, which is the primary way to interact with Scenic.

In this variant, the caller may register a request for focus management. The view_focuser’s client is coupled to the requested session, and this coupling acts as a security boundary: the ViewRef used as the basis for authority by view_focuser must come from session.

pub fn create_session_t( &self, endpoints: SessionEndpoints, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Create a new Session, which is the primary way to interact with Scenic.

In this variant, the caller may submit a combination of protocols that make sense for it. The Session protocol is the only required protocol. The SessionEndpoints table may be extended with more protocol fields, but these extensions should retain ABI and API compatibility with existing (pre-compiled) clients.

The response acknowledges the request to create a Session, but actual creation may happen later.

pub fn get_display_info( &self, ___deadline: MonotonicInstant, ) -> Result<DisplayInfo, Error>

Get information about the Scenic’s primary display.

pub fn get_display_ownership_event( &self, ___deadline: MonotonicInstant, ) -> Result<Event, Error>

Gets an event signaled with displayOwnedSignal or displayNotOwnedSignal when display ownership changes.

pub fn take_screenshot( &self, ___deadline: MonotonicInstant, ) -> Result<(ScreenshotData, bool), Error>

Take a screenshot and return the data in img_data. img_data will not contain BGRA data if success is false.

pub fn uses_flatland( &self, ___deadline: MonotonicInstant, ) -> Result<bool, Error>

Returns whether the clients should use [fuchsia.ui.composition/Flatland] protocol to interact with Scenic instead.

Trait Implementations

impl Debug for ScenicSynchronousProxy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SynchronousProxy for ScenicSynchronousProxy

type Proxy = ScenicProxy

The async proxy for the same protocol.

type Protocol = ScenicMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.

fn into_channel(self) -> Channel

Convert the proxy back into a channel.

fn as_channel(&self) -> &Channel

Get a reference to the proxy’s underlying channel.

fn is_closed(&self) -> Result<bool, Status>

Returns true if the proxy has received the PEER_CLOSED signal.
