Struct GraphRuntime 

pub struct GraphRuntime { /* private fields */ }

Orcha’s interface to the graph execution engine.

Serves as the factory for OrchaGraph handles. The lattice backend is an implementation detail — callers only ever see OrchaGraph.

Implementations

impl GraphRuntime

pub fn new(storage: Arc<LatticeStorage>) -> Self

pub fn storage(&self) -> Arc<LatticeStorage>

Expose the underlying lattice storage.

pub async fn create_graph(&self, metadata: Value) -> Result<OrchaGraph, String>

Create a new execution graph.

pub async fn create_child_graph( &self, parent_id: &str, metadata: Value, ) -> Result<OrchaGraph, String>

Create a new execution graph as a child of an existing graph.

pub async fn build_child_graph( &self, parent_id: &str, metadata: Value, nodes: Vec<OrchaNodeDef>, edges: Vec<OrchaEdgeDef>, ) -> Result<(String, HashMap<String, String>), String>

Build a child graph from node+edge definitions.

Creates the child graph under parent_id, adds all nodes, and wires all edges. Returns (child_graph_id, ticket_id→lattice_node_id map) on success.

pub fn open_graph(&self, graph_id: String) -> OrchaGraph

Open an existing graph by ID.

Trait Implementations

impl Clone for GraphRuntime

fn clone(&self) -> GraphRuntime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
