Enum CatalogRow 

pub enum CatalogRow<'a> {
    Absent,
    Kindless,
    Kind(&'a str),
}

What the runner’s catalog says about the requested model. Three cases, so a row that states no kind is never mistaken for a missing row.

Variants

Absent

The catalog has no row for the model.

Kindless

The row exists and states no kind.

Kind(&'a str)

The row states this kind.
