pub fn send_admin_request(
broker_endpoint: &str,
request: AdminRequest,
) -> Result<AdminReply, BrokerClientError>Expand description
Send one typed admin request to a broker endpoint and return its reply.
The blocking connect + write + read round-trip runs on a helper thread
bounded by broker_client_deadline (issue #590, cluster H); on
timeout the helper thread owns and drops the abandoned stream so a
stalled broker never wedges the caller.
