Struct FallbackTextAgent 

pub struct FallbackTextAgent { /* private fields */ }

Tries each child agent in sequence. Returns the first successful result. If all fail, returns the last error.

Implementations

impl FallbackTextAgent

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

Create a new fallback agent that tries candidates in order.

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

Attach a middleware chain. AgentEvent::FallbackActivated is emitted through it when a fallback branch (any candidate after the first) is tried, so on_event observers (M::on_fallback) fire.
