Struct stack_vm::Stack

pub struct Stack<T>(_);

A stack.

Supports only the most basic stack operations needed for the machine. Implemending using a Vec.

use stack_vm::Stack;
let mut stack: Stack<usize> = Stack::new();
assert!(stack.is_empty());

stack.push(13);
assert!(!stack.is_empty());

let value = stack.pop();
assert_eq!(value, 13);
