Wrap

Fields

types: Vec<ColumnType>
width: usize

Given n input expressions, wraps them into n / width rows, each of width columns.

This function is not intended to be called directly by end users, but is useful in the planning of e.g. VALUES clauses.

GenerateSubscriptsArray

Implementations

True iff the table function preserves the append-only property of its input.
