Lifecycle

Every service has a lifecycle, meaning it can be started and stopped. *

type lifecycle = {

name : string;
dependencies : unit -> lifecycle list;
start : unit -> unit Lwt.t;
stop : unit -> unit Lwt.t;

}

val create_lifecycle : 
  ?dependencies:(unit -> lifecycle list) ->
  ?start:(unit -> unit Lwt.t) ->
  ?stop:(unit -> unit Lwt.t) ->
  string ->
  lifecycle

Service

A service has a start and stop functions and a lifecycle. *

module Service : sig ... end

val start_services : Service.t list -> lifecycle list Lwt.t

start_services lifecycles starts a list of service lifecycles. The order does not matter as the services are started in the order of their dependencies. (No service is started before its dependency)

val stop_services : Service.t list -> unit Lwt.t

stop_services ctx services stops a list of service lifecycles with a context ctx. The order does not matter as the services are stopped in the order of their dependencies. (No service is stopped after its dependency)

module Map : sig ... end

val collect_all_lifecycles : lifecycle list -> lifecycle Map.t

val top_sort_lifecycles : lifecycle list -> lifecycle list

val unpack : string -> ?default:'a -> 'a option ref -> 'a
