Struct SubgraphNode 

Source 
pub struct SubgraphNode<S: StateSchema, SubS: StateSchema> { /* private fields */ }
Expand description

Subgraph Node - A node that executes a nested compiled graph

This allows composition of graphs by embedding one graph inside another. The subgraph receives mapped input state and returns mapped output state.
