Struct Stack 

pub struct Stack<T> {
    pub head: Option<Box<StackNode<T>>>,
    pub length: u16,
}

Fields

length: u16

Implementations

impl<T: Clone> Stack<T>

pub fn new() -> Self

pub fn pop(&mut self) -> Result<(usize, T), StackError>

pub fn push(&mut self, item: T) -> Result<usize, StackError>

where T: Clone,

pub fn dup(&mut self, index: usize) -> Result<(usize, T), StackError>

pub unsafe fn swap( &mut self, index: usize, ) -> Result<([usize; 2], [T; 2]), StackError>

Documentation

Safety

As Stack::swap, it swaps a specific item with the head of stack.

pub fn is_empty(&self) -> bool

pub fn peek(&self) -> Option<&T>

Trait Implementations

impl<T: Debug> Debug for Stack<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Default for Stack<T>

fn default() -> Self
