pub struct QueryPlan {
    pub relations_bound: bool,
    pub ctes: Vec<CtePlan>,
    pub root: RelationalPlan,
}

A relational query with its CTE scope and one relational root.

Fields

relations_bound: bool

Whether relation references in this tree are stored catalog identities rather than names that must be resolved in the executing session.

ctes: Vec<CtePlan>

root: RelationalPlan
