Struct PlayoutDeviceInfo 

pub struct PlayoutDeviceInfo {
    pub id: PlayoutDeviceId,
    pub name: String,
    pub index: usize,
}

Information about a playout (speaker) device.

This struct contains the device’s unique identifier, human-readable name, and index. Use the id field with PlatformAudio::set_playout_device() for type-safe device selection.

Platform Notes

• Desktop (Windows, macOS, Linux): Full device information is available. The id is a unique GUID, and name is a descriptive string (e.g., “MacBook Pro Speakers”).
• Android: Only a single device is reported with an empty id and name. Audio routing (speaker, earpiece, Bluetooth, wired headset) is handled by the system via AudioManager, not through WebRTC. Use AudioManager.setSpeakerphoneOn() to switch between speaker and earpiece on Android.

Example

let audio = PlatformAudio::new()?;
for device in audio.playout_devices() {
    println!("[{}] {} (ID: {})", device.index, device.name, device.id);
}

Fields

id: PlayoutDeviceId

The unique identifier for this device (stable across hot-plug events on desktop; empty on Android).

name: String

Human-readable device name (empty on Android).

index: usize

Device index (may change when devices are added/removed).
