Module `Eio_utils.Zzz`Source

A set of timers.

Sourcemodule Key : sig ... end

A handle to a registered timer.

Sourcetype t

A set of timers (implemented as a priority queue).

Sourcetype item =

| Fiber of unit Suspended.t
| Fn of unit -> unit

Sourceval create : unit -> t

create () is a fresh empty queue.

Sourceval add : t -> Mtime.t -> item -> Key.t

add t time item adds a new event, due at time, and returns its ID.

If item is a Fiber, you must use Eio.Private.Fiber_context.set_cancel_fn on it before calling pop. Your cancel function should call remove (in addition to resuming it).

Sourceval remove : t -> Key.t -> unit

remove t key removes an event previously added with add.

Source

val pop : 
  t ->
  now:Mtime.t ->
  [ `Due of item | `Wait_until of Mtime.t | `Nothing ]

pop ~now t removes and returns the earliest item due by now. For fibers, it also clears the thread's cancel function. If no item is due yet, it returns the time the earliest item becomes due.
