Module Lwt_main.Enter_iter_hooksSource

Hooks, of type unit -> unit, that are called before each iteration of the Lwt main loop.

  • since 4.2.0
Sourcetype 'return_value kind = 'return_value

Hooks are functions of either type unit -> unit or unit -> unit Lwt.t; this type constructor is used only to express both possibilities in one signature.

Sourcetype hook

Values of type hook represent hooks that have been added, so that they can be removed later (if needed).

Sourceval add_last : (unit -> unit kind) -> hook

Sourceval remove : hook -> unit

Removes a hook added by add_first or add_last.

Sourceval remove_all : unit -> unit
