Parameter Make.Pool
include Caqti.Pool.S with type 'a fiber := 'a System.Fiber.t
val size : ('a, 'e) t -> intsize pool is the current number of open resources in pool.
val use :
?priority:float ->
('a -> ('b, 'e) result System.Fiber.t) ->
('a, 'e) t ->
('b, 'e) result System.Fiber.tuse 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.
val drain : ('a, 'e) t -> unit System.Fiber.tdrain 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.
val create :
?config:Caqti.Pool.Config.t ->
?check:('a -> (bool -> unit) -> unit) ->
?validate:('a -> bool System.Fiber.t) ->

('a, 'e) tInternal: create alloc free is a pool of resources allocated by alloc and freed by free. This is primarily intended for implementing the connect_pool functions.
