Struct DeviceProxy

pub struct DeviceProxy { /* private fields */ }

Implementations

impl DeviceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.gpu.magma/Device.

pub fn take_event_stream(&self) -> DeviceEventStream

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

Panics

Panics if the event stream was already taken.

pub fn query( &self, query_id: QueryId, ) -> QueryResponseFut<DeviceQueryResult, DefaultFuchsiaResourceDialect>

On success, returns a result either in a buffer or a simple value.

pub fn connect2( &self, client_id: u64, primary_channel: ServerEnd<PrimaryMarker>, notification_channel: ServerEnd<NotificationMarker>, ) -> Result<(), Error>

Creates a connection to the device comprised of two IPC channels. The primary channel is for the Primary protocol (see below). The notification channel is used for vendor-specific messages which are sent only in the reverse (server-client) direction, typically in response to client command completion.

fn into_channel(self) -> Result<AsyncChannel, Self>

Attempt to convert the proxy back into a channel.

fn as_channel(&self) -> &AsyncChannel

Get a reference to the proxy’s underlying channel.

fn into_client_end(self) -> Result<ClientEnd<Self::Protocol>, Self>

Attempt to convert the proxy back into a client end.

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
