MutableStack

type t('a);

let make: unit => t('a);

Returns a new stack, initially empty.

let clear: t('a) => unit;

Discard all elements from the stack.

let copy: t('a) => t('a);

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

let push: (t('a), 'a) => unit;

let popUndefined: t('a) => Js.undefined('a);

let pop: t('a) => option('a);

let topUndefined: t('a) => Js.undefined('a);

let top: t('a) => option('a);

let isEmpty: t('a) => bool;

let size: t('a) => int;

let forEachU: (t('a), [@bs] ('a => unit)) => unit;

let forEach: (t('a), 'a => unit) => unit;

let dynamicPopIterU: (t('a), [@bs] ('a => unit)) => unit;

let dynamicPopIter: (t('a), '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.
