Struct ToolNode 

pub struct ToolNode { /* private fields */ }

A node that executes tool calls from the AI’s response.

ToolNode reads tool calls from the last AI message and executes them in parallel, returning the results as tool messages.

Implementations

impl ToolNode

pub fn new(tools: Vec<Arc<dyn BaseTool>>) -> Self

Create a new ToolNode with the given tools.

pub fn with_error_handling(self, handle: bool) -> Self

Set whether to handle tool errors gracefully (returning error messages instead of propagating).

pub fn tool_names(&self) -> Vec<&str>

Get the list of available tool names.

Trait Implementations

impl Runnable for ToolNode

fn invoke( &self, input: &JsonValue, config: &RunnableConfig, ) -> Result<JsonValue, RunnableError>

Execute synchronously.

fn ainvoke<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, input: &'life1 JsonValue, config: &'life2 RunnableConfig, ) -> Pin<Box<dyn Future<Output = Result<JsonValue, RunnableError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Execute asynchronously.

fn name(&self) -> &str

Human-readable name for tracing/debugging.
