Subgraphs

A subgraph is a compiled graph used as a node in another graph. Use this for modular, reusable workflows.

Embedding a Subgraph

#![allow(unused)]
fn main() {
let inner = inner_graph.compile(CompileConfig::default())?;
outer_graph.add_subgraph("inner", inner);
}

The outer graph invokes the inner graph as a single node. When the outer graph reaches “inner”, it runs the full inner graph to completion.

Namespace Isolation

Subgraphs use independent checkpoint namespaces. Their state is stored separately from the parent graph, which avoids key collisions and simplifies debugging.

Event Bubbling

Internal events from the subgraph surface to the parent via SubgraphEvent. The parent can observe or react to subgraph activity without coupling to its internals.
