Function: readRowset()

readRowset(value): RowsetReading | undefined

Defined in: src/integrity/column-types/check.ts:117

READ a finished result as a rowset, or decline to.

The one readable shape, and why only this one: an ARRAY OF PLAIN OBJECTS with at least one row. That is what a rowset is on this wire, it is what every consumer named in the docs page already expects, and it is the same Array.isArray law the neighbouring check reads by — the two must never disagree about what a rowset is.

undefined (⇒ not-applicable, a ROW) for everything else: • a non-array — prose, a null, a { rows: [...] } wrapper, a ticket; • an array holding anything that is not a plain object — a list of strings has no columns, and inventing some is how a checker starts lying; • an array of ZERO rows — an empty answer has no columns to be wrong about, and it is the neighbour's subject, not this one's.
