pub struct ReActLoop { /* private fields */ }

The ReAct agent loop.

Implementations

impl ReActLoop

pub fn new(config: AgentConfig) -> Self

Create a new ReActLoop with the given configuration and an empty tool registry.

pub fn register_tool(&mut self, spec: ToolSpec)

Register a tool that the agent loop can invoke.

pub async fn run<F, Fut>( &self, prompt: &str, infer: F, ) -> Result<Vec<ReActStep>, AgentRuntimeError>

where F: FnMut(String) -> Fut, Fut: Future<Output = String>,

Execute the ReAct loop for the given prompt.

Arguments

• prompt — user input passed as the initial context
• infer — async inference function: receives context string, returns response string

Returns

• Ok(Vec<ReActStep>) — steps executed, ending with a FINAL_ANSWER step
• Err(AgentRuntimeError::AgentLoop) — if max iterations reached without FINAL_ANSWER or if a ReAct response cannot be parsed
