Internal: create alloc free is a pool of resources allocated by alloc and freed by free. This is primarily indented for implementing the connect_pool functions.

parameter max_size
Maximum number of resources to allocate at any given time.

parameter check
A function used to check a resource after use.

parameter validate
A function to check before use that a resource is still valid.

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 future) ->
  ('a, 'e) t ->
  ('b, 'e) result future

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

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 future

drain pool closes all resources in pool. The pool is still usable, as new resources will be created on demand.
