class AudioDeviceRegistry
Defined at line 35 of file ../../src/media/audio/services/device_registry/audio_device_registry.h
This singleton coordinates device detection, serves the outgoing FIDL, and maintains lists of
pending, active and unhealthy Devices. The object should live for the duration of the service.

void AudioDeviceRegistry (std::shared_ptr<FidlThread> server_thread)Defined at line 32 of file ../../src/media/audio/services/device_registry/audio_device_registry.cc
void ~AudioDeviceRegistry ()Defined at line 38 of file ../../src/media/audio/services/device_registry/audio_device_registry.cc
zx_status_t StartDeviceDetection (bool ignore_devices)Kick off device-detection. After AddDevice, the device auto-initializes and then calls one of
DeviceIsReady, DeviceHasError or DeviceIsRemoved.

const std::unordered_set<std::shared_ptr<Device>> & devices ()Device support
The set of active (successfully initialized) devices.
Defined at line 50 of file ../../src/media/audio/services/device_registry/audio_device_registry.h
const std::unordered_set<std::shared_ptr<Device>> & unhealthy_devices ()The set of devices that encountered an error. A device should never be in both sets.

void InitialDeviceDetectionComplete ()The DeviceDetector has notified us of any devices that existed when device detection began.
(It will continue to notify us if additional devices are detected.)
These initially-detected devices might still be in the initialization process, but if not, then
notify all Registry servers that they may begin responding to WatchDevicesAdded calls.

void AddDevice (const std::shared_ptr<Device> & initializing_device)Add a newly-constructed Device object to our "initializing" list.

void DeviceIsReady (std::shared_ptr<Device> ready_device)A device has completed initialization and can be moved into the set of "ready" devices.
If this was an initially-detected device, then check whether we can now allow Registry servers to
respond to WatchDevicesAdded calls.

void DeviceIsRemoved (std::shared_ptr<Device> device_to_remove)Entirely remove the device, including from the unhealthy list.
