Module Lwt_main.Exit_hooksSource

Promise-returning hooks, of type unit -> unit Lwt.t, that are called at process exit. Exceptions raised by these hooks are ignored.

  • since 4.2.0
Sourcetype 'return_value kind = 'return_value Lwt.t

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_first : (unit -> unit kind) -> hook

Adds a hook to the hook sequence underlying this module, to be run first, before any other hooks already added.

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

Adds a hook to the hook sequence underlying this module, to be run last, after any other hooks already added.

Sourceval remove : hook -> unit

Removes a hook added by add_first or add_last.

Sourceval remove_all : unit -> unit

Removes all hooks from the hook sequence underlying this module.
