: sig

Interaction with the garbage collector

This module offer a convenient way to add a finaliser launching a thread to a value, without having to use Lwt_unix.run in the finaliser.

#
val finalise : ('a -> unit Lwt.t) -> 'a -> unit

finalise f x ensures f x is evaluated after x has been garbage collected. If f x yields, then Lwt will waits for its termination at the end of the program.

Note that f x is not called at garbage collection time, but latter in the main loop.

#
val finalise_or_exit : ('a -> unit Lwt.t) -> 'a -> unit

finalise_or_exit f x call f x when x is garbage collected or (exclusively) when the program exit.

end
