Struct Node 

pub struct Node<T: State> {
    pub name: String,
    pub function: NodeFunction<T>,
    pub mcps: Vec<String>,
    pub config: HashMap<String, Value>,
    /* private fields */
}

A compiled node ready for execution.

This is created internally by the runtime when configuration is loaded.

Fields

name: String

Node name (identifier)

function: NodeFunction<T>

The actual handler function to execute

mcps: Vec<String>

MCP tools available to this node

config: HashMap<String, Value>

Custom configuration

Implementations

impl<T: State> Node<T>

pub fn new( name: impl Into<String>, function: NodeFunction<T>, mcps: Vec<String>, config: HashMap<String, Value>, ) -> Self

Create a new compiled node.

pub fn new_placeholder( name: impl Into<String>, function: NodeFunction<T>, mcps: Vec<String>, config: HashMap<String, Value>, ) -> Self

Create a placeholder node (identity function that will be replaced via register_node).

pub fn new_planner( name: impl Into<String>, function: NodeFunction<T>, mcps: Vec<String>, config: HashMap<String, Value>, ) -> Self

Create a planner node (LLM-driven dynamic next-node selection).

pub async fn execute(&self, state: T) -> Result<T>

Execute this node with the given state.

Returns

The updated state after node execution, or an error. Returns an error if the node handler was never registered (still a placeholder).
