Struct RowsExpectation 

pub struct RowsExpectation {
    pub columns: Option<Vec<String>>,
    pub unordered: bool,
    pub rows: Option<Vec<Vec<Expectation>>>,
    pub bound: Option<CountBound>,
}

The sql-target row-shape expectation: exactly one row shape is populated at parse time — concrete row patterns or a row-count bound (rows XOR bound).

columns names the projection the assertion applies to; it is applied at the call site, which projects the observed rows by column name before matching (ADR-0072 §3 — the algebra is parameterized, observation is per-tier).

Fields

columns: Option<Vec<String>>

Optional projection: the column names the observed rows are narrowed to before matching, applied by name at the call site.

unordered: bool

Whether the rows may match in any order; false matches positionally in declaration order.

rows: Option<Vec<Vec<Expectation>>>

Concrete row patterns, one expectation per projected cell. Populated exactly when bound is None.

bound: Option<CountBound>

Row-count bound over the projected rows. Populated exactly when rows is None.
