Struct NullOutput 

pub struct NullOutput;

Null output handler that discards all events (useful for testing and backward compatibility)

Trait Implementations

impl AgentOutput for NullOutput

fn emit_event<'life0, 'async_trait>( &'life0 self, _event: AgentEvent, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

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

Emit token usage update

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

Emit warning message

fn error<'life0, 'life1, 'async_trait>( &'life0 self, content: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), Box<dyn Error + Send + Sync>>> + Send + 'async_trait>>

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

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

Request a confirmation decision from the output handler (UI/API) Default: deny (safe). Concrete outputs (CLI/UI) should override to prompt.

fn supports_realtime_updates(&self) -> bool

Check if this output handler supports real-time updates
