Enum SoleRole 

pub enum SoleRole {
    Sole,
}

The role roster of a kind that renders exactly one unit, at the declaration site.

Not a placeholder and not an absence: a kind whose rendering is one unit says so with a roster of one, and a kind whose one unit lands elsewhere declares its own.

Variants

Sole

The kind’s one rendered unit.
