Struct QueryPlan 

pub struct QueryPlan {
    pub join_order: Vec<String>,
    pub access_paths: Vec<AccessPath>,
    pub join_segments: Vec<JoinPlanSegment>,
    pub total_cost: f64,
    pub morsel_eligibility: Option<MorselEligibility>,
}

The final output of the query planner: an ordered access plan.

Fields

join_order: Vec<String>

Tables in the chosen join order.

access_paths: Vec<AccessPath>

Access path for each table (parallel to join_order).

join_segments: Vec<JoinPlanSegment>

Join operator segments selected for execution/explain.

total_cost: f64

Total estimated cost in page reads.

morsel_eligibility: Option<MorselEligibility>

Morsel-parallel SELECT eligibility (populated after planning).

Trait Implementations

impl Clone for QueryPlan

fn clone(&self) -> QueryPlan

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryPlan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for QueryPlan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for QueryPlan

fn eq(&self, other: &QueryPlan) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
