Module node 

Node definition for LangGraph

Nodes are the execution units in a graph. Each node receives the current state and returns a state update.

Structs

AsyncNode

AsyncNode - Simple async node wrapper

FunctionNode

Function-based node implementation

InterruptibleNode

Resume-aware node (LangGraph-style interrupt).

NodeConfig

Node configuration

SentinelNode

Placeholder node for entry/exit points

SyncNode

Simple sync node wrapper

Constants

INTERRUPT_RESUME_KEY

Metadata key the compiled graph uses to inject the human’s decision into a node that is being resumed after a runtime crate::errors::GraphError::InterruptRequest. A resume-aware node reads the value under this key from its NodeConfig.metadata.

Traits

AsyncFn

AsyncFn trait for simpler async node creation

GraphNode

Graph Node trait

Type Aliases

AsyncNodeFn

Async node function type (boxed future)

NodeResult

Node execution result (alias for clarity)
