Class `Lwt_engine.abstract`

Abstract class for engines.

method destroy : unit: Destroy the engine, remove all its events and free its associated resources.

method transfer : abstract -> unit: transfer engine moves all events from the current engine to engine. Note that timers are reset in the destination engine, i.e. if a timer with a delay of 2 seconds was registered 1 second ago it will occur in 2 seconds in the destination engine.

Event loop methods

method virtual iter : bool -> unit
method on_readable : Unix.file_descr -> (event -> unit) -> event
method on_writable : Unix.file_descr -> (event -> unit) -> event
method on_timer : float -> bool -> (event -> unit) -> event
method fake_io : Unix.file_descr -> unit
method readable_count : int
method writable_count : int
method timer_count : int

Backend methods

method private virtual cleanup : unit: Cleanup resources associated with the engine.

method private virtual register_readable : Unix.file_descr -> (unit -> unit) -> unit Stdlib.Lazy.t
method private virtual register_writable : Unix.file_descr -> (unit -> unit) -> unit Stdlib.Lazy.t
method private virtual register_timer : float -> bool -> (unit -> unit) -> unit Stdlib.Lazy.t
