val use : ?priority:float -> ('a -> ('b, 'e) Stdlib.result Lwt.t) -> ('a, 'e) t -> ('b, 'e) Stdlib.result Lwt.t

use f pool calls f on a resource drawn from pool, handing back the resource to the pool when f exits.

    Requests for the resource are handled in decreasing order of priority. The default priority is 0.0.
