val run : t ‑> f:(unmanaged_t, 'query, 'response) Parallel.Function.t ‑> arg:'query ‑> 'response Core.Or_error.t Async.Deferred.t

run t and run_exn t will connect to t if there is not already a connection, but if there is currently a connection that has gone stale, they will fail with an error. Trying again will attempt a reconnection.

val run_exn : t ‑> f:(unmanaged_t, 'query, 'response) Parallel.Function.t ‑> arg:'query ‑> 'response Async.Deferred.t

val kill : t ‑> unit Core.Or_error.t Async.Deferred.t

Using these functions will not result in on_failure reporting a closed connection, unlike running the shutdown function.
