Struct PlayoutDeviceId 

pub struct PlayoutDeviceId(/* private fields */);

Unique identifier for a playout (speaker) device.

This is a type-safe wrapper around the platform-specific device GUID. Obtain this from PlayoutDeviceInfo returned by PlatformAudio::playout_devices().

Platform Notes

• Desktop (Windows, macOS, Linux): Contains a unique GUID that persists across device hot-plug events. Use this for reliable device selection.
• Android: Always empty. Android doesn’t provide device GUIDs and only reports a single “default” device. Audio routing (speaker, earpiece, Bluetooth) is handled by the system via AudioManager, not through WebRTC device selection.

Example

let audio = PlatformAudio::new()?;
for device in audio.playout_devices() {
    println!("{}: {}", device.name, device.id);
    // Save device.id for later use (desktop only)
}
