val push : 'a t -> 'a -> unit
val popUndefined : 'a t -> 'a Js.undefined
val pop : 'a t -> 'a option
val topUndefined : 'a t -> 'a Js.undefined
val top : 'a t -> 'a option
val isEmpty : 'a t -> bool
val size : 'a t -> int
val forEachU : 'a t -> ('a -> unit) -> unit
val forEach : 'a t -> ('a -> unit) -> unit
val dynamicPopIterU : 'a t -> ('a -> unit) -> unit
val dynamicPopIter : 'a t -> ('a -> unit) -> unit

dynamicPopIter s f apply f to each element of s. The item is poped before applying f, s will be empty after this opeartion. This function is useful for worklist algorithm
