Executors

AutoAgents ships with two primary executors. You can also implement your own by conforming to AgentExecutor.

• Basic: single‑turn chat without tool calls
• ReAct: multi‑turn reasoning with tool calls and streaming

Basic

Use BasicAgent<T> to run a single prompt/response cycle. Suitable for simple Q&A and when tools are not needed.

Key points:

• No tool calls
• Optional streaming variant
• Output type: BasicAgentOutput → convert to your agent output via From<...>

#![allow(unused)]
fn main() {
use autoagents::core::agent::prebuilt::executor::BasicAgent;
let agent = BasicAgent::new(MyAgent);
}

ReAct

Use ReActAgent<T> for iterative reasoning + acting. Supports tool calls, multi‑turn loops (with max_turns), and streaming with intermediate events.

Key points:

• Tool calls are serialized, executed, and their results fed back to the LLM
• Emits events: tool requested/completed, turn started/completed, stream chunks
• Output type: ReActAgentOutput → convert to your agent output via From<...>

#![allow(unused)]
fn main() {
use autoagents::core::agent::prebuilt::executor::ReActAgent;
let agent = ReActAgent::new(MyAgent);
}

Tip: ReActAgentOutput::extract_agent_output<T> can deserialize a structured JSON response into your type when you expect strict JSON.
