Enum HotplugEvent 

pub enum HotplugEvent {
    Arrived(MtpDeviceInfo),
    Left(MtpDeviceInfo),
}

A device was plugged in or unplugged.

Only MTP devices produce events; see DeviceWatch for what the stream guarantees.

Deliberately not #[non_exhaustive]: a device is either here or it isn’t, and there’s no third state to grow into. Consumers get an exhaustive match instead of a dead wildcard arm. The payload carries MtpDeviceInfo, which is #[non_exhaustive], so new device facts still land without breaking anyone.

Variants

Arrived(MtpDeviceInfo)

A device appeared, or was already present when watching began.

Left(MtpDeviceInfo)

A device went away. The info is what the watch last saw for it.
