Enum Lookup 

#[non_exhaustive]
pub enum Lookup {
    On,
    Off(Reason),
    NoRow,
}

What the matrix says about one capability on one (backend, version, config).

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.

On

A matching row says yes and no matching row says no.

Off(Reason)

A matching row says no, for this reason.

NoRow

No row matches: untested, therefore off.
