Module type `Stack_intf.Stack`

A stack implemented with an array.

The implementation will grow the array as necessary, and will never automatically shrink the array. One can use set_capacity to explicitly resize the array.

module type S = S

include S

val min_elt : 'a t -> compare:('a -> 'a -> int) -> 'a option
val max_elt : 'a t -> compare:('a -> 'a -> int) -> 'a option
val of_list : 'a list -> 'a t: of_list l returns a stack whose top is the first element of l and bottom is the last element of l.

val create : unit -> 'a t: create () returns an empty stack.

val singleton : 'a -> 'a t: singleton a creates a new stack containing only a.

val push : 'a t -> 'a -> unit: push t a adds a to the top of stack t.

val pop : 'a t -> 'a option: pop t removes and returns the top element of t as Some a, or returns None if t is empty.

val pop_exn : 'a t -> 'a
val top : 'a t -> 'a option: top t returns Some a, where a is the top of t, unless is_empty t, in which case top returns None.

val top_exn : 'a t -> 'a
val clear : 'a t -> unit: clear t discards all elements from t.

val copy : 'a t -> 'a t: copy t returns a copy of t.

val until_empty : 'a t -> ('a -> unit) -> unit: until_empty t f repeatedly pops an element a off of t and runs f a, until t becomes empty. It is fine if f adds more elements to t, in which case the most-recently-added element will be processed next.

val capacity : _ t -> int: capacity t returns the length of the array backing t.

val set_capacity : _ t -> int -> unit: set_capacity t capacity sets the length of the array backing t to max capacity (length t). To shrink as much as possible, do set_capacity t 0.
