Struct WorkflowDag 

pub struct WorkflowDag { /* private fields */ }

Authoring graph containing workflow nodes, edges, and canvas metadata.

Implementations

impl WorkflowDag

pub fn new(nodes: Vec<WorkflowDagNode>, edges: Vec<WorkflowDagEdge>) -> Self

Construct a DAG programmatically. Hosts that compile an authoritative product format can use this path without serializing through YAML or JSON first.

pub fn from_json(source: &str) -> Result<Self, WorkflowDslError>

Parses a graph from JSON without document-level validation.

pub fn from_yaml(source: &str) -> Result<Self, WorkflowDslError>

Parses a graph from YAML without document-level validation.

pub fn to_json(&self) -> Result<String, WorkflowDslError>

Serializes the graph, including presentation fields, as JSON.

pub fn nodes(&self) -> &[WorkflowDagNode]

Returns nodes in their source authoring order.

pub fn edges(&self) -> &[WorkflowDagEdge]

Returns edges in their source authoring order.

pub fn viewport(&self) -> Option<&Value>

Returns optional canvas viewport metadata.

pub fn extensions(&self) -> &BTreeMap<String, Value>

Returns unknown graph fields preserved during round trips.

pub fn node(&self, id: &str) -> Option<&WorkflowDagNode>

Looks up a node by its stable graph identity.

pub fn execution_plan(&self) -> Result<WorkflowDagPlan, WorkflowDslError>

Validates graph structure and derives deterministic per-scope order.

pub fn execution_digest(&self) -> Result<String, WorkflowDslError>

Derive a stable identity for executable graph semantics. Canvas layout and authoring order do not affect this digest.
