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.

Unavailable

not possible here (browser without EyeDropper, Android, no X server / portal)

Denied

the app’s permissions lack screen.capture, or the system / the user refused

Cancelled

the user cancelled (Esc, a right click, the portal’s dialog dismissed)

Busy

a pick (or capture) is still running

Failed(String)

the system failed: what it said
