Struct EffectiveExecutionGraph 

pub struct EffectiveExecutionGraph {
    pub source: ExecutionGraphSource,
    pub nodes: HashMap<String, ExecutionGraphNode>,
    pub edges: Vec<ExecutionGraphEdge>,
    pub entry: Option<String>,
}

Fully materialized execution graph used by the runtime scheduler.

Fields

source: ExecutionGraphSource

Planner or fallback source that produced the graph.

nodes: HashMap<String, ExecutionGraphNode>

Node map keyed by node id.

edges: Vec<ExecutionGraphEdge>

Directed edges between nodes.

entry: Option<String>

Optional entry node selected for execution start.

Implementations

impl EffectiveExecutionGraph

pub fn add_node(&mut self, node: ExecutionGraphNode) -> Result<()>

Adds a node and rejects duplicate ids.

pub fn add_edge(&mut self, edge: ExecutionGraphEdge) -> Result<()>

Adds an edge after verifying that both endpoint nodes exist.

pub fn get_node(&self, node_id: &str) -> Option<&ExecutionGraphNode>

Returns one node by id.

pub fn outgoing_edges( &self, node_id: &str, ) -> impl Iterator<Item = &ExecutionGraphEdge> + '_

Iterates over outgoing edges for one node.

pub fn incoming_count(&self, node_id: &str) -> usize

Counts incoming edges for one node.

pub fn validate(&self) -> Result<()>

Validates entry-point references and rejects cyclic graphs.
