Struct RaceTextAgent 

pub struct RaceTextAgent { /* private fields */ }

Runs agents concurrently, returns the first to complete. Cancels the rest.

Implementations

impl RaceTextAgent

pub fn new(name: impl Into<String>, agents: Vec<Arc<dyn TextAgent>>) -> Self

Create a new race agent that runs agents concurrently and returns the first result.

pub fn with_middleware_chain(self, chain: MiddlewareChain) -> Self

Attach a middleware chain. AgentEvent::AgentStarted is emitted through it for every contender as the race starts and AgentEvent::AgentCompleted once, for the winner; losers are cancelled silently.

Trait Implementations

impl TextAgent for RaceTextAgent

fn name(&self) -> &str

Human-readable name for logging and debugging.

fn run<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 State, ) -> Pin<Box<dyn Future<Output = Result<String, AgentError>> + Send + 'async_trait>>

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

Execute this agent. Reads/writes state. Returns the final text output.

fn run_with<'life0, 'life1, 'async_trait>( &'life0 self, request: RunRequest, state: &'life1 State, ) -> Pin<Box<dyn Future<Output = Result<RunResult, AgentError>> + Send + 'async_trait>>

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

Run one request and report everything it produced: the reply, the turns to append to a conversation, token usage and tool calls.

fn run_stream<'a>( &'a self, request: RunRequest, state: State, ) -> BoxStream<'a, Result<RunEvent, AgentError>>

Run one request as a stream of RunEvents: text as the model writes it, each tool call and result, then RunEvent::Finished.

fn stream( &self, prompt: impl Into<String>, ) -> BoxStream<'_, Result<RunEvent, AgentError>>

where Self: Sized,

Stream the reply to one question, with no history and fresh state.

fn ask<'life0, 'async_trait>( &'life0 self, prompt: impl 'async_trait + Into<String> + Send, ) -> Pin<Box<dyn Future<Output = Result<String, AgentError>> + Send + 'async_trait>>

where Self: Sized + 'async_trait, 'life0: 'async_trait,

Ask one question, with no history and fresh state, and get the reply.

fn ask_as<'life0, 'async_trait, T>( &'life0 self, prompt: impl 'async_trait + Into<String> + Send, ) -> Pin<Box<dyn Future<Output = Result<T, AgentError>> + Send + 'async_trait>>

where Self: Sized + 'async_trait, T: DeserializeOwned + JsonSchema + Send + 'async_trait, 'life0: 'async_trait,

Ask one question and get the reply as a T.

fn chat(&self) -> Chat<&Self>

where Self: Sized,

Start a conversation that remembers its turns. See Chat.
