Module payload 

Payload trait and PayloadNode for integrating external work units.

The Payload trait is the boundary between the graph orchestrator and external execution logic (e.g., LLM calls from llm-pipeline). The graph runtime never implements payload logic — it only orchestrates execution.

Structs

PayloadContext

Context passed to payloads during execution.

PayloadNode

A node that wraps a Payload for execution within the graph.

PayloadOutput

Output from a payload execution.

Traits

Payload

A unit of work that can be executed by the graph runtime.

Type Aliases

InputSelector

Function that extracts payload input from graph state.

OutputMapper

Function that maps payload output back into graph state.

PayloadError

Error type for payload invocations.

TokenCallback

Token callback type for streaming.
