Module Belt_MutableStack

First in last out stack.

This module implements stacks, with in-place modification.

type 'a t
val make : unit -> 'a t
  • returns

    a new stack, initially empty.

val clear : 'a t -> unit

Discard all elements from the stack.

val copy : 'a t -> 'a t

copy x O(1) operation, return a new stack

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) Js.Fn.arity1 -> unit
val forEach : 'a t -> ('a -> unit) -> unit
val dynamicPopIterU : 'a t -> ('a -> unit) Js.Fn.arity1 -> 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
