Struct ObservePlan 

pub struct ObservePlan {
    pub shape: PlanShape,
    pub index_reads: u64,
    pub required_nodes: u64,
    pub will_materialize: Vec<String>,
    pub will_not_materialize: Vec<String>,
}

The plan for one observation. required_nodes and the materialization lists are deterministic estimates derived from the selector and index shape; they do not require loading node bodies.

Fields

shape: PlanShape

The selected shape.

index_reads: u64

Index descents the observation will perform.

required_nodes: u64

Seed nodes the observation is expected to fetch.

will_materialize: Vec<String>

Node kinds / byte classes that will be materialized.

will_not_materialize: Vec<String>

Node kinds / byte classes that will not be materialized.
