Module query 

Cypher query planning and execution engine.

Contains the logical planner, executor, DataFusion integration, predicate pushdown, rewrite rules, and supporting utilities.

Leaf modules (df_udfs, datetime, spatial, df_expr, expr_eval, cypher_type_coerce, function_props, fusion, pushdown, rewrite, similar_to) live in the uni-query-functions crate and are re-exported below so downstream callers can keep using uni_query::query::<name>::*.

Modules

cypher_type_coerce

Cypher Type Coercion Layer

datetime

Temporal functions for Cypher query evaluation.

df_expr

Translation layer from Cypher expressions to DataFusion expressions.

df_graph

Custom graph operators for DataFusion execution.

df_planner

Hybrid physical planner for DataFusion integration.

df_udaf_plugin

DataFusion adapter for uni_plugin::traits::aggregate::AggregatePluginFn.

df_udfs

Cypher-specific User Defined Functions (UDFs) for DataFusion.

df_udfs_plugin

Plugin-registry scalar-UDF integration for DataFusion.

executor

Query execution engine.

expr_eval

Expression evaluation helper functions.

function_props

fusion

Score fusion algorithms for combining results from multiple search sources.

locy_planner

Locy plan builder — translates a CompiledProgram into a LogicalPlan::LocyProgram.

planner

planner_locy_types

Supporting types for Locy logical plan variants.

pushdown

Predicate pushdown and index-aware query routing.

rewrite

similar_to

similar_to() expression function — unified similarity scoring.

spatial

Constants

WINDOW_FUNCTIONS

Supported window function names (uppercase). Used by both planner and executor for consistency.
