}

A protocol for setting up watchers of usage gain.

Variants

RegisterListener

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.

Fields

device_unique_id: String

usage: Usage

usage_gain_listener: ClientEnd<UsageGainListenerMarker>

control_handle: UsageGainReporterControlHandle

RegisterListener2

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.

Fields

device_unique_id: String

usage: Usage2

usage_gain_listener: ClientEnd<UsageGainListenerMarker>

control_handle: UsageGainReporterControlHandle

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: UsageGainReporterControlHandle

method_type: MethodType
