Struct Stack

pub struct Stack<T: Debug + PartialEq>(pub Vec<T>);

Tuple Fields

0: Vec<T>

Implementations

impl<T: Debug + PartialEq> Stack<T>

pub fn new() -> Stack<T>

Constructs an empty stack.

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

This function pushes the given value on to the stack.

Arguments

value - The value to push on to the stack.

pub fn pop(&mut self, pos: usize) -> Result<T, Error>

This function pop the top value on to the stack. This may result in an error if the stack is empty.

Arguments

pos - The position where the pop was called. This is used if there was error.

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

This function returns a reference to the top value on the stack, without consuming it. If the stack is empty, None is returned.

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

This function returns a reference to the top value on the stack, without consuming it. If the stack is empty, None is returned.

pub fn is_empty(&self) -> bool

This function returns true if there are no elements in the stack.

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

Formats the value using the given formatter.
