Struct HotplugEvent 

#[non_exhaustive]
pub struct HotplugEvent {
    pub card: Option<PathBuf>,
    pub connector_id: Option<u32>,
}

One connector changing.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

card: Option<PathBuf>

The card the kernel named, usually /dev/dri/cardN.

Absent when the uevent carried no DEVNAME. Owned rather than borrowed from the udev device, which is freed as soon as the event has been read.

connector_id: Option<u32>

Which connector, when the kernel says.

The CONNECTOR=<id> hint arrived in 4.16. Absent on older kernels, and absent on the blanket events a GPU reset produces – and absent is not “nothing changed”, it is “re-enumerate everything”, because the alternative is a display that was plugged in and never noticed.
