See Hello, world! in the user guide and uv_timer_t — Timer handle in libuv.

type t = [ `Timer ] Handle.t

Binds uv_timer_t.

Note that values of this type can be passed to functions in Luv.Handle, in addition to the functions in this module. In particular, see Luv.Handle.close.

val init : ?loop:Loop.t -> unit -> (t, Error.t) Stdlib.result

Allocates and initializes a timer.

val start : ?call_update_time:bool -> ?repeat:int -> t -> int -> (unit -> unit) -> (unit, Error.t) Stdlib.result

Starts a timer.

Binds uv_timer_start.

As of Luv 0.5.7 and libuv 1.41.0 (March 2021), this function can fail only if the timer handle is currently closing, i.e.

Luv.Handle.is_closing timer = true
val stop : t -> (unit, Error.t) Stdlib.result

Stops a timer.

Binds uv_timer_stop.

val again : t -> (unit, Error.t) Stdlib.result

Restarts a timer.

Binds uv_timer_again.

val set_repeat : t -> int -> unit

Sets the timer repeat interval.

Binds uv_timer_set_repeat.

val get_repeat : t -> int
