quic.EndpointOptions.idleTimeout

The number of seconds an endpoint will remain alive after all sessions have closed and it is no longer listening. A value of 0 (default) means the endpoint is only destroyed when explicitly closed via endpoint.close() or endpoint.destroy(). A positive value starts an idle timer when the endpoint becomes idle; if no new sessions are created before the timer fires, the endpoint is automatically destroyed. This is useful for connection pooling where endpoints should linger briefly for reuse by future connect() calls.
