AgentSession

gemini_adk_rs::agent_session

Struct AgentSession 

Source 
pub struct AgentSession { /* private fields */ }
Expand description

Intercepting wrapper around a SessionWriter.

Adds input fan-out, middleware hooks, and state tracking without introducing a second queue (avoids double-queuing).
