module Ivar: Ivar
type 'a t
include Invariant.S1
val equal : 'a t -> 'a t -> bool
equal t t' is physical equality of t and t'.
val create : unit -> 'a t
create () returns an empty ivar.
val fill : 'a t -> 'a -> unit
fill t v fills t with value v if t was empty. If t was full, fill raises
an exception.
val fill_if_empty : 'a t -> 'a -> unit
fill_if_empty t v fills t with v if t is currently empty. If t is full,
then fill_if_empty does nothing.
val is_empty : 'a t -> bool
is_empty t returns true if t is empty
val is_full : 'a t -> bool
is_full t returns true if t is full
The Raw interface and Deferred module exposed here are for async's internal use
only. They must be exported here because we want the Deferred.t and Ivar.t types
to be fully abstract, so that they show up nicely in type errors, yet other async
code defined later needs to deal with the raw types.
include Raw
module Deferred: sig .. end
val read : 'a t -> 'a Deferred.t
read t returns a deferred that becomes enabled with value v after the ivar is
filled with v.
