# Module Core_stack

    module Core_stack: sig .. end

A stack implemented with an array. See `Stack_intf` for documentation.

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.

    include Stack_intf.S

    val capacity : 'a t -> int

`capacity t` returns the length of the array backing `t`.

    val set_capacity : 'a 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`.
