Struct FactoryProxy 

pub struct FactoryProxy { /* private fields */ }

Implementations

impl FactoryProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ultrasound/Factory.

pub fn take_event_stream(&self) -> FactoryEventStream

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

Panics

Panics if the event stream was already taken.

pub fn create_capturer( &self, request: ServerEnd<AudioCapturerMarker>, ) -> QueryResponseFut<(Clock, AudioStreamType), DefaultFuchsiaResourceDialect>

Creates a new fuchsia.media.AudioCapturer that is capable of capturing audio in the ultrasonic frequency range.

The capturer will be suitible for capturing audio at ultrasound frequencies. The channelization and sample rate of the capturer will be fixed to whatever the underlying device is configured for. The fuchsia.media.AudioSampleFormat will be FLOAT.

See fuchsia.media.AudioCore for more information on the operation of a fuchsia.media.AudioCapturer, with the following differences:

• SetUsage is disallowed. Ultrasound capturers do not have an associated fuchsia.media.AudioCaptureUsage.

• BindGainControl is disallowed. Ultrasound capturers will always have unity gain.

• SetPcmStreamType is disallowed. The stream type of an ultrasound capturer is not configurable, but instead returned from CreateCapturer.

• SetReferenceClock is disallowed. The reference clock of an ultrasound capturer is not configurable, but instead returned from CreateCapturer.

pub fn create_renderer( &self, renderer: ServerEnd<AudioRendererMarker>, ) -> QueryResponseFut<(Clock, AudioStreamType), DefaultFuchsiaResourceDialect>

Creates a new fuchsia.media.AudioRenderer that is capable of producing audio in the ultrasonic frequency range.

The renderer will be suitible for producing audio at ultrasound frequencies. The channelization and sample rate of the renderer will be fixed to whatever the underlying device is configured for. The fuchsia.media.AudioSampleFormat will be FLOAT.

See fuchsia.media.AudioCore for more information on the operation of a fuchsia.media.AudioRenderer, with the following differences:

• SetUsage is disallowed. Ultrasound renderers do not have an associated fuchsia.media.AudioRenderUsage2.

• BindGainControl is disallowed. Ultrasound renderers will always have unity gain.

• SetPcmStreamType is disallowed. The stream type of an ultrasound renderer is not configurable, but instead returned from CreateRenderer.

• SetReferenceClock is disallowed. The reference clock of an ultrasound renderer is not configurable, but instead returned from CreateRenderer.

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<'_, NullableHandle>>

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