Struct PlanStatement 

pub struct PlanStatement {
    pub statement: SqlStatement,
    pub guard: Option<AffectedRowGuard>,
}

One statement in a plan, paired with the guard (if any) that validates it. Runner contract: a present guard is checked against the affected-row count of applying statement alone (SqlWriter::execute’s return value), or the result-row count for a GTD no-op read assertion, not a batch total and not another statement’s count. guard: None means prepare made no row-existence assumption about this particular statement (e.g. a cascade delete that may legitimately touch zero rows).

Fields

statement: SqlStatement

The DML, or GTD no-op SELECT assertion, to apply inside the atomic unit.

guard: Option<AffectedRowGuard>

The expected-effect guard for statement, if prepare’s validation assumed a target row exists for it.
