Struct QueryPlanner 

pub struct QueryPlanner { /* private fields */ }

Implementations

impl QueryPlanner

pub fn new(schema: Arc<Schema>) -> Self

pub fn with_params(self, params: HashMap<String, Value>) -> Self

Set query parameters for resolving $param references in SKIP/LIMIT.

pub fn plan(&self, query: Query) -> Result<LogicalPlan>

pub fn plan_with_scope( &self, query: Query, vars: Vec<String>, ) -> Result<LogicalPlan>

pub fn plan_pattern( &self, pattern: &Pattern, initial_vars: &[VariableInfo], ) -> Result<LogicalPlan>

Plan a MATCH pattern into a LogicalPlan (Scan → Traverse chains).

This is a public entry point for the Locy plan builder to reuse the existing pattern-planning logic for clause bodies.

pub fn properties_to_expr( &self, variable: &str, properties: &Option<Expr>, ) -> Option<Expr>

pub fn node_filter_expr( &self, variable: &str, labels: &[String], properties: &Option<Expr>, ) -> Option<Expr>

Build a filter expression from node properties and labels.

This is used for TraverseMainByType where we need to filter target nodes by both labels and properties. Label checks use hasLabel(variable, ‘label’).

impl QueryPlanner

pub fn explain_plan(&self, ast: Query) -> Result<ExplainOutput>

pub fn explain_logical_plan(&self, plan: &LogicalPlan) -> Result<ExplainOutput>
