Struct DefaultBackgroundTaskHandler 

pub struct DefaultBackgroundTaskHandler { /* private fields */ }

Opt-in default message/send handler wired up by [A2AServerBuilder::with_default_background_task_handler] / [A2AServerBuilder::with_default_task_handlers].

When an Agent is configured, delegates to the inference gateway via a single non-streaming generate_content call and returns the resulting task with state == Completed and the reply attached. Without an agent, returns the static [NO_AGENT_REPLY] message - processWithoutAgentBackground.

Implementations

impl DefaultBackgroundTaskHandler

pub fn new(agent: Option<Arc<Agent>>) -> Self

pub fn set_enable_usage_metadata(&mut self, enable: bool)

Override whether terminal tasks carry usage / execution_stats metadata. A2AServerBuilder calls this to honour AgentConfig::enable_usage_metadata.

pub fn is_usage_metadata_enabled(&self) -> bool

Whether terminal tasks will carry usage/execution metadata.
