Struct QueryPlan 

Source 
pub struct QueryPlan {
    pub query: String,
    pub tree: PlanTree,
    pub shape: PlanShape,
    pub result_columns: Vec<String>,
}
Expand description

Result of Database::explain.

Fields§

§query: String

The exact query text the caller submitted.

§tree: PlanTree

Operator tree, leaf-most first under each node.

§shape: PlanShape

Whether running this plan would (potentially) mutate the graph.

§result_columns: Vec<String>

Result column names in projection order. Empty for plans without a top-level projection (e.g. plans that only mutate).
