Struct ShortRepresentation

pub struct ShortRepresentation {
    pub description: Option<String>,
    pub subqueries: Option<HashMap<String, i32>>,
}

Condensed representation of a node and its subtree. Only present for SCALAR PlanNode(s).

This type is not used in any activity, and only used as part of another schema.

Fields

description: Option<String>

A string representation of the expression subtree rooted at this node.

subqueries: Option<HashMap<String, i32>>

A mapping of (subquery variable name) -> (subquery node id) for cases where the description string of this node references a SCALAR subquery contained in the expression subtree rooted at this node. The referenced SCALAR subquery may not necessarily be a direct child of this node.
