An SQL values.
Fields§
§explicit_row: boolWhether each row is written with the explicit ROW( ... ) row constructor
(MySQL’s query-position spelling — VALUES ROW(1, 2), ROW(3, 4)) rather than a
bare ( ... ) row (VALUES (1, 2), (3, 4), the PostgreSQL/DuckDB/SQLite/ANSI
spelling). A single flag, not a per-row bit, because the spelling is uniform across
the constructor: MySQL requires ROW on every row and syntax-rejects the bare form
(SelectSyntax::values_row_constructor off), while
the others require the bare form (that gate on). Preserving it keeps the ROW
keyword round-tripping — the same explicit axis
the UPDATE ... SET (a, b) = ROW(...) tuple source and the Expr::Row value
constructor already carry.
rows: ThinVec<ThinVec<ValuesItem<X>>>rows in source order.
meta: MetaSource location and node identity.

Erase to

Clone into a fresh box — the object-safe stand-in for

fn dyn_eq(&self, other: &dyn DynAstExt) -> bool
Structural equality against another erased node — the object-safe stand-in
for
PartialEq (whose &Self argument cannot go through a vtable). Equal
iff other holds the same concrete type and that type deems the values
equal; differently-typed nodes are never equal.
