Struct Stack

pub struct Stack<T>(/* private fields */);

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);

Implementations

impl<T: Debug> Stack<T>

pub fn new() -> Stack<T>

pub fn is_empty(&self) -> bool

Returns true if the stack contains no elements.

pub fn push(&mut self, value: T)

Push an element onto the top of the stack.

pub fn pop(&mut self) -> T

pub fn peek(&self) -> &T

Take a sneaky look at the top element on the stack.

pub fn peek_mut(&mut self) -> &mut T

Make a sneaky change to the top element on the stack.

pub fn as_slice(&self) -> &[T]
