Enum FilterScope 

pub enum FilterScope {
    Page,
    Universe,
}

What the caller declares --filter may observe.

Absent, the surface refuses a predicate over a truncated page rather than answering about a set it never saw. Present, the caller has said which reading it meant, and the surface obeys.

Variants

Page

Judge only the rows the query returned, and say so in the record.

Universe

Require the predicate to observe the whole universe.

Identical to the default today; declaring it makes the requirement explicit in a script that must not silently start filtering a page if a limit is added later.
