Struct ModuleDagBuilder 

pub struct ModuleDagBuilder { /* private fields */ }

Fluent builder for ModuleDagDefinition.

Collects nodes automatically from .edge() calls. Entry nodes and the nodes list are both derived automatically when .build() is called, so callers only need to describe the edges between node definitions.

Implementations

impl ModuleDagBuilder

pub fn new() -> Self

pub fn edge(self, from: &ModuleDagNodeDef, to: &ModuleDagNodeDef) -> Self

Registers a directed edge from → to.

Both nodes are inserted into the node registry on first encounter (subsequent calls with the same node_id are silently ignored so the same ModuleDagNodeDef reference is safe to reuse across calls).

pub fn node(self, node: &ModuleDagNodeDef) -> Self

Registers an isolated node (no edges). Useful for single-node DAGs.

pub fn default_policy(self, policy: DagNodeExecutionPolicy) -> Self

Sets a default execution policy applied to every node.

pub fn build(self) -> ModuleDagDefinition

Consumes the builder and produces a ModuleDagDefinition.

Entry nodes are derived as any node that never appears as a to in an edge.

Trait Implementations

impl Default for ModuleDagBuilder

fn default() -> Self

Returns the “default value” for a type.
