Crate uni_query 

Query execution layer for the Uni graph database.

This crate provides OpenCypher query parsing, logical planning, and execution against Uni’s object-store-backed property graph.

Modules

• query — planner, executor, DataFusion integration, pushdown logic
• types — public value types (Value, Node, Edge, Path, etc.)

Quick Start

let executor = Executor::new(storage);
let planner = QueryPlanner::new(schema);
let plan = planner.plan(cypher_ast)?;
let result = executor.execute_plan(plan, &params).await?;
