    fn agent(
        &self,
        agent_name: Option<&str>,
        parent: Option<&TraceContext>,
    ) -> Box<dyn AgentObserver>;
    fn tool_call_request(
        &self,
        tool_name: &str,
        parent: Option<&TraceContext>,
    ) -> Box<dyn McpRequestInstrumentation>;

Required Methods

fn agent( &self, agent_name: Option<&str>, parent: Option<&TraceContext>, ) -> Box<dyn AgentObserver>

A fresh observer for one agent, continuing the parent trace when supplied.
