Implementations

impl UsageGainReporterSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<UsageGainReporterEvent, 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 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.
