DTuple is the tuple Datum.

// DTuple is the tuple Datum.
type DTuple struct {
	D Datums

	// sorted indicates that the values in D are pre-sorted.
	// This is used to accelerate IN comparisons.
	sorted bool

	// typ is the tuple's type.
	//
	// The Types sub-field can be initially uninitialized, and is then
	// populated upon first invocation of ResolvedTypes(). If
	// initialized it must have the same arity as D.
	//
	// The Labels sub-field can be left nil. If populated, it must have
	// the same arity as D.
	typ *types.T
}

// maybePopulateType populates the tuple's type if it hasn't yet been
// populated.
