Struct OperatorNode 

pub struct OperatorNode {
    pub operator: OperatorPlan,
    pub target_nodes: Vec<u64>,
    pub cost: CostEstimate,
}

One node in the ExecutionPlan tree. Carries the operator shape + the executor-targeting metadata.

Fields

operator: OperatorPlan

The operator + its operator-specific parameters.

target_nodes: Vec<u64>

node_ids that hold the data this operator reads. Empty for nodes that don’t touch the substrate directly (e.g. a top-of-tree Project that runs at the caller). Ordered lexicographically for determinism.

cost: CostEstimate

Cost estimate for this operator alone (not the subtree). Phase A populates conservatively; phases B–E refine.

Trait Implementations

impl Clone for OperatorNode

fn clone(&self) -> OperatorNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperatorNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OperatorNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for OperatorNode

fn eq(&self, other: &OperatorNode) -> 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.

impl Serialize for OperatorNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
