Struct UsageGainReporterProxy 

pub struct UsageGainReporterProxy { /* private fields */ }

Implementations

impl UsageGainReporterProxy

pub fn new(channel: Channel) -> Self

Create a new Proxy for fuchsia.media/UsageGainReporter.

pub fn take_event_stream(&self) -> UsageGainReporterEventStream

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

Panics

Panics if the event stream was already taken.

pub fn register_listener( &self, device_unique_id: &str, usage: &Usage, usage_gain_listener: ClientEnd<UsageGainListenerMarker>, ) -> Result<(), Error>

Connects a listener to a stream of usage gain setting changes for usage on the device identified by device_token. Usage Gain is not set directly by any client; it is a translation of the usage volume setting for each device, summed with active muting/ducking gain adjustments.

Devices may map the same volume level to different dbfs, so a device_unique_id is needed to identify the device.

AudioDeviceEnumerator provides programmatic access to devices and their unique ids if it is necessary for a client to select an id at runtime.

pub fn register_listener2( &self, device_unique_id: &str, usage: &Usage2, usage_gain_listener: ClientEnd<UsageGainListenerMarker>, ) -> Result<(), Error>

Connects a listener to a stream of usage gain setting changes for usage on the device identified by device_token. Usage Gain is not set directly by any client; it is a translation of the usage volume setting for each device, summed with active muting/ducking gain adjustments.

Devices may map the same volume level to different dbfs, so a device_unique_id is needed to identify the device.

Trait Implementations

impl Clone for UsageGainReporterProxy

fn clone(&self) -> UsageGainReporterProxy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UsageGainReporterProxy

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

Formats the value using the given formatter.

impl Proxy for UsageGainReporterProxy

type Protocol = UsageGainReporterMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.

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

Attempt to convert the proxy back into a channel.

fn as_channel(&self) -> &Channel

Get a reference to the proxy’s underlying channel.

fn domain(&self) -> Arc<Client>

Get the client supporting this proxy. We call this a “domain” here because:

fn on_closed(&self) -> OnFDomainSignals

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