Implementations

impl DynamicExecutionPlan

pub fn new() -> Self

Create a new empty execution plan

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

Add a node to the plan

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

Add an edge to the plan

pub fn get_entry_nodes(&self) -> Vec<&WorkflowNode>

Get nodes that have no incoming edges (starting points)

pub fn get_exit_nodes(&self) -> Vec<&WorkflowNode>

Get nodes that have no outgoing edges (endpoints)

pub fn get_outgoing_edges(&self, node_id: &str) -> Vec<&WorkflowEdge>

Get outgoing edges from a node

pub fn get_incoming_edges(&self, node_id: &str) -> Vec<&WorkflowEdge>

Get incoming edges to a node

pub fn has_cycles(&self) -> bool

Check for cycles in the DAG

pub fn topological_sort(&self) -> Result<Vec<String>>

Topological sort (returns nodes in execution order) Returns Err if there are cycles

pub fn find_next_nodes( &self, current_node_id: &str, context: &StepPrehookContext, ) -> Vec<String>

Returns the next nodes whose edge conditions pass for the current context.

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

Returns one node by identifier.

pub fn is_completed(&self, state: &DagExecutionState) -> bool

Returns true when every exit node is marked completed in the execution state.
