Struct GraphPlan 

pub struct GraphPlan {
    pub ir_version: IrVersion,
    pub dialect: String,
    pub ontology_version: Option<OntologyVersion>,
    pub ontology_mode: OntologyMode,
    pub feature_flags: Vec<String>,
    pub ops: Vec<GraphOp>,
    pub exprs: ExprArena,
}

A versioned, serialisable graph query plan.

GraphPlan is the stable contract between the binder and the execution engine. It carries the full operator pipeline, all referenced expressions in a flat ExprArena, and the ontology metadata needed by the relational lowering layer.

Construction

Use GraphPlan::builder rather than constructing this directly:

use graphforge_ir::{GraphPlan, GraphOp, VarId};

let plan = GraphPlan::builder("openCypher")
    .push_op(GraphOp::NodeScan { var: VarId(0), ty: None })
    .build();

assert_eq!(plan.ops.len(), 1);
assert_eq!(plan.dialect, "openCypher");

Fields

ir_version: IrVersion

IR format version for forward-compatibility checks.

dialect: String

Query dialect (e.g. "openCypher").

ontology_version: Option<OntologyVersion>

Ontology version used when the plan was compiled.

None in Exploratory mode (no formal ontology present).

ontology_mode: OntologyMode

Active ontology enforcement mode.

feature_flags: Vec<String>

Optional feature flags that affect plan behaviour.

ops: Vec<GraphOp>

The operator pipeline (in execution order).

exprs: ExprArena

All expressions referenced by operators in this plan.

Implementations

impl GraphPlan

pub fn builder(dialect: impl Into<String>) -> GraphPlanBuilder

Create a GraphPlanBuilder for constructing a new plan.

dialect identifies the query language (e.g. "openCypher"). The builder defaults to ir_version = IrVersion::CURRENT and ontology_mode = OntologyMode::Exploratory.
