Module `Caqti_lwt_unix.Pool`Source

Sourcetype ('a, +'e) t

Sourceval size : ('a, 'e) t -> int

size pool is the current number of open resources in pool.

Source

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

use f pool calls f on a resource drawn from pool, handing back the resource to the pool when f exits. The result returned by f is not used by Caqti, but allows flattening errors into a single polymorphic variant type.

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

Sourceval drain : ('a, 'e) t -> unit Lwt.t

drain pool closes all resources in pool once they become idle. The pool is still usable, as new resources will be created on demand. Resources are not closed while they are in use.
