pub async fn sync_session(state: &DispatchState, task_id: &str) -> Result<()>Expand description
Publish the current projection of one session.
The frame is the client’s heartbeat report carrying the whole projection:
one frame per session activity, and the only one that puts a session’s state
on the wire. session_id is the row the server keys the mirror by, which for
a client-held session is its task id.
