Struct PatternPlan 

pub struct PatternPlan {
    pub path_var: Option<BindingId>,
    pub search: Option<PathPrefixPlan>,
    pub start: NodeStep,
    pub steps: Vec<(EdgeStep, NodeStep)>,
}

Fields

path_var: Option<BindingId>

Binding for the whole path value (kind == BindingKind::Path).

search: Option<PathPrefixPlan>

The lowered path-search / path-mode prefix, or None when the pattern carried no prefix (the default: every path, edge-unique WALK). A search other than All/None is only ever set on a pattern with exactly one quantified segment, anchored forward on its start (the lowering enforces both), so the executing operator’s source is the pattern’s start node.

start: NodeStep

steps: Vec<(EdgeStep, NodeStep)>

Multi-hop chain: each step is an edge followed by the node it reaches.
