Enum Source 

#[non_exhaustive]
pub enum Source {
    Udev,
    Kernel,
}

Where the uevents are read from.

Not a detail on the machines drmkit is for. A desktop has udevd, which applies its rules and only then republishes the event – by which point the device node exists with the right permissions. A minimal embedded init often has no udevd at all, and a monitor waiting for one to republish waits forever, so the display that was plugged in is never noticed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Udev

What udevd republishes. The right answer where udevd runs.

Kernel

The kernel’s own netlink broadcast, which arrives whether or not anything else is listening.
