Trait AgentObserver 

pub trait AgentObserver: Send {
    // Required method
    fn on_event(&mut self, message: &AgentEvent);

    // Provided method
    fn tool_trace_context(&self, _tool_id: &str) -> Option<TraceContext> { ... }
}

Observer of the agent’s event stream. Observers receive the same events the agent sends on its event channel, synchronously and in order — including events that channel consumers such as UIs and session persistence filter out downstream.

Required Methods

fn on_event(&mut self, message: &AgentEvent)

Provided Methods

fn tool_trace_context(&self, _tool_id: &str) -> Option<TraceContext>

Trace context to propagate to whatever executes tool_id, available once the observer has seen that tool’s ExecutionStarted.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
